Day-5: Mastering Python Loops

Python Boot Camp-2023: Day-5

Python Loop: A Powerful Tool for Iterative Tasks Python, one of the most popular programming languages, offers a wide range of features and functionalities. Among these, loops stand out as a powerful tool for performing repetitive tasks. In this article, we’ll explore Python loops, their types, usage, and best practices to optimize your code. 1. Introduction to Python Loops Loops are essential…

I'm taking a class on like. advanced data structures and blah blah whatever blah. riveting stuff. Anyway one the main things we're being taught in the class is runtime optimization which makes sense. but like. why is it being taught in python of all languages

[artsekey]

I'm trying to learn how to code in Python for my job and I feel like I hit a programing rite of passage by making a nested for and while loop with no exit condition 👌

CAFFEINE, CODE, AND COUCH CONFESSIONS

Warnings: coffee addiction

Tim Drake, the resident tech genius of Wayne Manor, had a mission: to teach you the intricacies of coding. Armed with a whiteboard, a stack of textbooks, and a steely determination, he embarked on this noble quest. Little did he know that unraveling the mysteries of Python and JavaScript would be the least challenging part.

Tim sat you down in the cozy corner of the Batcave, the glow of the Batcomputer casting shadows on his face. He explained loops, variables, and functions with the fervor of a preacher. But your brain? It was like a stubborn old laptop running Windows 95—slow, glitchy, and prone to crashing.

"Okay, so if you have a nested loop," Tim said, pointing at the whiteboard, "you'll need to—"

You interrupted. Again. "Wait, wait. What's a nested loop? Is it like a Russian doll situation?"

Tim sighed, rubbing his temples. "No, it's not—"

"But what if the Russian doll is an array?" you asked, eyes wide.

Tim's patience wavered. "It's not—"

"But what if the array contains Batman's utility belt gadgets?" you persisted.

He pinched the bridge of his nose. "That's not—"

Coding fatigue set in. Tim's eyes glazed over as you continued your relentless questioning. He needed a distraction—a break from the syntax and semicolons. So, he proposed a truce: "How about we take a snack break?"

You perked up. "Snacks? Now you're speaking my language."

Soon, the Batcave echoed with the rustling of chip bags and the clinking of coffee mugs. Tim brewed a fresh pot of coffee—the fifth one that day—and you raised an eyebrow.

"Tim, you're going to turn into a jittery metahuman," you warned.

He grinned, sipping from his mug. "Nah, I've built up a tolerance."

The couch beckoned, its cushions inviting. Tim abandoned the whiteboard, and you both sank into its plush embrace. Laptops forgotten, you fired up the gaming console. The Batcave's massive screen displayed the latest multiplayer shooter.

"Ready to kick some virtual butt?" you asked, controller in hand.

Tim hesitated. "Actually, can we watch movies instead?"

You raised an eyebrow. "Movies? Since when do you—"

"—binge-watch romantic comedies?" Tim finished, cheeks flushing. "I may or may not have a soft spot for cheesy love stories."

And so, you traded code for rom-coms, coffee for popcorn. Tim's head found its way to your lap, and you stroked his hair absentmindedly.

"Promise me," you said, "no more coffee. Your heart rate is rivaling the Bat-Signal."

He grumbled but complied. "Fine. But only because you're the best code-cracking partner."

As the credits rolled on the screen, Tim whispered, "Maybe I'll write an algorithm to predict our next movie choice."

You chuckled. "Or we could just flip a coin."

And there, in the dim glow of the Batcave, you realized that maybe—just maybe—love was the most complex code of all.

All Right, Let's Do a Dumb One

LeetCode has a bunch of problems that are at this point almost famous for how laughably unrepresentative they are of work in the coding world. Like, there are points where demonstrating that you can solve one also incidentally demonstrates that you know certain kinds of critical thinking, and those questions are genuinely quite good, but most of the time it's just a Credit Score kind of thing where what you demonstrate is that you spent time practicing on LeetCode, and therefore the site made itself necessary by getting enough business decision-makers to trust it. Anyway.

This is a good example because if I got this as a question during the interview the first thing I'd do is include a disclaimer.

The challenge is to rotate an image 90 degrees. The "image" is represented by a 2D array numbered, so this happens. 123 741 456 -> 852 789 963

Now, the question says they want you to change it in-place, meaning no making a new array and slotting things in. The disclaimer I'd include is: This is a terrible idea. Making a 2D array - even a very large one, such as the kind you'd need to display something hi-def on an IMAX theater screen - is not horribly memory-intensive in the scale of memory that our computers work with today. And working in-place is terribly error-prone, both in initial creation (which someone could theoretically lay at your feet - shouldn't you be good enough to get around that?) AND in maintenance, meaning even if I know I'M hypercompetent at coding and can do it all in-place, I'm metaphorically making a bridge out of hard-to-replace materials and setting that bridge up to fall apart when the maintenance guy doesn't know how to repair it. Not doing it the way they demand you do it for the question would be part of coding best practices.

But what the hell. Let's do it. For the sake of argument.

I'd still be doing a microcosm of the same. You have to record what's in a slot without deleting it.

I'm wondering whether the intent is to run this via breadth-first search, in order to work out which spaces have already been processed? I'm going to go on that assumption.

So in a Rubik's Cube kind of way, I'm going to start from the corners. Because they're the easiest to mathematically transform to each other regardless of size, right? We're supposed to be able to do this whether the square we're rotating is 3x3 or 300x300. For a mercy, it is at least guaranteed to be a square.

We make a (starts off empty) list of processed spaces.

We make a (starts off empty) list of spaces to look at.

for x, y what happens on "rotate" exactly? In terms of corners, for an nxn grid (0, 0) gets moved to (n-1, 0) which gets moved to (n-1, n-1) which gets moved to (0, n-1) which gets moved to (0, 0). Like, in a 4x4 grid (3, 3)'s contents get moved to (0, 3). What about that second space? (1, 0) turns into (3, 1). (2, 0) turns into (3, 2). So for the top row at least, you can reverse the x and y values and invert the number of the y value, and that does it?

...I think this means you want depth-first search, actually. Because you want to be handling the square each time in order to minimize how much info you're holding at a time.

What happens is you make a nested for loop, like

for i in array: for j in list: while (i,j) not in fixed: {Block of code that adds the 4 permutations of (x,y), (-y-1,x), (-x-1,-y-1), (y,-x-1) to a list for processing and then processes them in order, finally adding i,j to fixed when it's done}

The reason this works in Python is that calling for "-1" in a list is the same as saying "length of the list -1." So on a 4x4, calling "-x-1" when x is 0 will loop around the other side of the list to find the 3.

At that point, you're only holding two points of data - the item you've just "picked up" from a given space and then the contents of the space you'll be "putting it down" in. Then you swap it out for what's in the target location.

Again, this would all be a LOT easier to just do by writing to a new list.

At that point, for each space you'd just find the space 90 degrees counterclockwise from it and set that value into the corresponding space.

Fun Stuff this week

🍻 met up with my bestie @muakrrr <3 it was a stressful tuesday so meeting him for lunch was super comforting! he bought this cute purple drink and I got myself some ginger ale and the waiter served us the wrong drinks (gender and expectations something something) and it was amusing to watch them get confused when we corrected them 🎂 mom's b'day this week!! went out for dinner with her!! 🛒 went shopping with relatives who I haven't seen in years. bought myself a book! (rip my bookshelf) ☕ went out for coffee and dinner with my girlies (the same besties who I exchanged mugs with). we're trying to spend as much time together as possible before we leave to different countries for our masters 🎮 continuing the beginner's guide 📺 ongoing: Marry my Husband, Cherry Magic Th, Last Twilight 📺 binged: KinnPorsche The Series

📻 This week's soundtrack

Love Wins All by IU (been crying over this music video for days now. it's beautiful) KinnPorsche theme by Slot Machine: Kinn's theme [aka Phiang Waichai; TH] | Porche's theme [aka Free Fall; Eng] (first of all this is one of the catchiest theme songs to exist second only to SPECIALZ aka the JJK s2 op i'm also particularly losing my mind over how the two themes are love letters to the main characters from each other... the narrative parallels of it all are driving me insane sldkhlaksjkshs) Dum Dum by Jeff Satur + the Live Unchained version where his vocals are heavenly (maybe im so drawn to this song because the chorus is similar to the melodic motifs of the KPTS themes/soundtrack, either way, the show introduced me to him and god. I've been voraciously consuming his discography.) Ghost by Jeff Satur (on repeat all week. thoroughly obsessed with this song- the lyricism, his voice, the storyline in the MV, his acting, everything. wow. truly.)

---

[Jan 22 to 28 ; week 4/52 || I. love. my. internship. like. I have been having the most fun time problem solving and troubleshooting. it's also super satisfying to see the outcome of my code. it's been a while since I used python (I've been coding on C) so I forget that python has a lot of inbuilt functions that would do the same tasks I inadvertently entrust my nested loops with, and finding out about them is always so joyous (although it means I have to scrap off several chunks of code). i am a bit annoyed though, because the other intern isn't really doing any work that we're entrusted with so I'm having to carry the team and it's taking me too much time. but oh well. I've suggested we split tasks from next week, hopefully that'll make things better.

I've also been procrastinating a lot when it comes to my masters applications and it really hit me this week when I had to run to uni several times to get things approved and completed. Now that I'll get to work from home I need to set up a proper schedule to get application work completed wayy in advance. also need to resume my GRE prep from next week.]

Iterations - for loop

Iteration, aka repeating, is a solution for tasks that need to be done over and over again.

Instead of writing dozens of lines of code for the same purpose, we can simplify it and shorten it to just a couple of lines. This way the code is both easier to read for the other programmers (fellow people hehe) and faster to process for the computer.

Also, simpler code reduces errors rate.

Examples of iterations are loops.

Looping means repeating something until a particular condition is satisfied. 

Python has 3 Basic Loops:

For Loop - used when we know number of iterations (repetitions) in advance.

While Loop - for situations where the number of iterations is unknown beforehand. 

Nested Loop - using one looping statement inside another looping statement.

For loop is used to execute the same instruction over and over again, a specific number of times.

for i in range(5):     print(“Hello!”) Output: Hello! Hello! Hello! Hello! Hello!

In the first line, we declared how many repetitions are needed. In the second line, we wrote what should be repeated a given number of times. In this case, we asked Python to print the string “Hello!” 5 times.

Basic structure of the for loop:

for i in range(5):     print(“Hello!”)

for - a keyword that signals that “for loop” is starting.

i - internal variable name which is keeping the counter value. Stands for “iteration”. We can read the whole line as “for 5 iterations/repetitions, please do the following:” For every loop, the 'i' variable increases by 1 because it's the counter. 'i' doesn't have to be 'i', we can switch it to another letter or another word, that are python approved for this (for example, you can’t use name of defined function instead of 'i').

#Loop using "unicorn" as internal variable, instead of "i" for unicorn in range(10): print(unicorn) #still works!

  in range() - represents the list of numbers we are looping through (number of time the iteration is running). Python starts the counter from 0. It means that range(5) -  will give a sequence of 5 numbers: 0, 1, 2, 3, 4 range() function has 3 parameters(start, end, steps), default values for start is 0 and step is 1. When we write range(5), we only give one parameter, and the function still works, because Python reads it as range(0,5,1) and the sequence starts with 0, increases by 5 counts, with step between each number being 1, by default.

We can change the parameters: range(1,20,3) this would result in iterations that starts from 1, goes up by 3 steps with the upper limit of 20: 1, 4,7,10,13,16,19.

Example: #print every 2 numbers (evens): for i in range (2, 10, 2):     print(x) output: 2 4 6 8 (!) output does not include 10 because 10 is the upper limit (result only includes number under 10)

: adding a colon sign in the end of the first line is mandatory, otherwise an error will occur.   Finally in the next line, we start writing the instruction, that is supposed to be repeated. This part isn’t starting right away, it should be indented. Indentation is the blank gap at the beginning of lines. Normal indentation is 4 spaces/tab long. Python would recognize 2 spaces or 4 spaces as an indentation, but 4 spaces length is more agreed upon and is used more wildly.

tip: How to write an instruction to get output of a list that starts from 1 instead of 0, accompanied by a string:

for i in range(10):     print(i+1, "I love you")

Python Loops Tutorial | Loops In Python | Python Loops Tutorial for Beginners

Let's go through a basic tutorial on loops in Python. This tutorial is designed for beginners, and we'll cover the two main types of loops in Python: for and while loops.

1. For Loop:

The for loop is used to iterate over a sequence (such as a list, tuple, string, or range).# Example 1: Iterate over a list fruits = ["apple", "banana", "cherry"] for fruit in fruits: print(fruit) # Output: # apple # banana # cherry # Example 2: Iterate over a range of numbers for i in range(5): print(i) # Output: # 0 # 1 # 2 # 3 # 4

2. While Loop:

The while loop is used to repeatedly execute a block of code as long as the specified condition is true.# Example 3: Simple while loop count = 0 while count < 5: print(count) count += 1 # Output: # 0 # 1 # 2 # 3 # 4

3. Loop Control Statements:

break: Terminates the loop.

continue: Skips the rest of the code inside the loop for the current iteration.

else clause with loops: Executed when the loop condition becomes False.

# Example 4: Using break and continue for i in range(10): if i == 3: continue # Skip the rest of the code for this iteration elif i == 8: break # Exit the loop when i is 8 print(i) else: print("Loop completed") # Output: # 0 # 1 # 2 # 4 # 5 # 6 # 7

4. Nested Loops:

You can use loops inside other loops.# Example 5: Nested loops for i in range(3): for j in range(2): print(f"({i}, {j})") # Output: # (0, 0) # (0, 1) # (1, 0) # (1, 1) # (2, 0) # (2, 1)

This is a basic introduction to loops in Python. Practice with different examples to solidify your understanding. In Part 2, you can explore more advanced concepts and practical applications of loops in Python.

Oh man, if only I had the power to write a math curriculum that incorporated programming concepts like vector arithmetic, object-oriented algebra, algorithm card games... and in high school kids should learn how to use python to do the math for them. Imagine telling your students that they can use a calculator to do all of the math for them, so long as they build the calculator themselves!

def the_exponenterrr(x, n, a, c): y = a*x**n + c return y

I started playing around with RPG Maker 2000 when it was new, and even though all I ever did was pretty basic event-scripting, it was still quite foundational to my understanding of how to code by teaching me loops, variables, nested-ifs, and more!

The fact that there’s an actually functional website for the library of Babel is one of those things that fucks me up more and more the more I think about the implications.
