What Is a Dynamically Typed Language?

When learning Python, you might hear the term “dynamically typed language” frequently. But what does it mean? Let’s break it down.

Typing refers to type-checking—the process of verifying whether the data types in your code are compatible with the operations being performed.

1️⃣ Strongly vs. Weakly Typed Languages

Strongly-Typed Languages (e.g., Python): These languages don’t allow type-coercion (implicit type conversion). For example:

pythonCopy code"1" + 2  # TypeError: cannot concatenate 'str' and 'int'

Weakly-Typed Languages (e.g., JavaScript): These languages allow type-coercion:

javascriptCopy code"1" + 2  // Outputs: "12"

2️⃣ Static vs. Dynamic Typing

Type-checking can occur at two stages:

Static Typing (e.g., Java, C++): Data types are checked before the program runs. You must declare the type of variables explicitly:

javaCopy codeintx=10; 

Dynamic Typing (e.g., Python): Data types are checked during program execution. Variable types are inferred automatically:

pythonCopy codex = 10  # No need to declare 'x' as an integer.

Python: A Dynamically Typed Language

Since Python is an interpreted language, it executes code line by line. Type-checking happens on the fly, allowing you to write flexible and concise code.

Example: pythonCopy codex = "Hello"x = 10  # No error—Python allows 'x' to change types.

This flexibility makes Python beginner-friendly but also increases the risk of runtime errors if types are misused.

Key Takeaway

Dynamic typing simplifies coding by removing the need for explicit type declarations. However, it also requires careful testing to ensure type-related bugs don’t creep in.

Python learners, embrace dynamic typing—it’s one of the reasons Python is so versatile and fun to use!

Python Day 2

Today I am starting off with exercise 13. Exercise 13 introduces the concepts of variables, modules, and argv.

[ID: Exercise 13 code. It imports the argv module from sys, then uses argv to create 4 variables, script, first, second, and third. Next print() is used to print out the different variables /ID]

When calling the program I was confused as to why I got the error of too many variables. Looking into this I found that the first variable of 'argv' is always going to be the script. I then fixed that and added in script as the first variable.

Next for the study drill I wrote a new variable and updated the code to print the retrieved information.

Alrighty then - onto exercise 14. Exercise 14 is about practicing prompts and variables.

In the study drills I updated the script with a new prompt and print statement.

Exercise 15 is a simple program that prints out the contents of a file. An important thing to note is to always close the file when doing things like this!

Exercise 16 practices making a copy of a file and then updating it with 3 lines from user input.

I ended up running into the issue where it was saying that it couldn't read the file. I ended up finding out that .read() starts from the cursor position - and if the cursor is at the end of the file from writing it you will not have your file printed.

Exercise 17 is practicing copying files over and was relatively simple.

Memory Optimization in Pandas: Why category Sometimes Uses MORE Memory!    

Have you ever tried converting a Pandas column to category dtype, expecting less memory usage only to find it increased instead? 🤯 Let’s break it down! Using dtype={'column': 'category'} should reduce memory usage because: ✅ It stores unique values separately and uses integer codes to reference them. ✅ It works best for columns with many repeated values (e.g., product categories, country names). Hidden Insight 🔎 : If your dataset has many unique values, category dtype adds overhead instead of saving space. Here's why: ❌ Every unique value needs its own entry in the category mapping. ❌ If your column had short text values (e.g., 'NY', 'CA'), the original object type was already optimized. ❌ category needs extra storage for mapping each value to an integer index. You can run a quick test to see memory usage differences as given in the code.

In short; If the column has repeated values, category saves space. If the column has mostly unique values, category uses more memory than object. Use category only when: 👉 The column has a limited number of unique values (e.g., department, product type). 👉 You plan to group, filter, or analyze categories frequently. 👉 The column was using object dtype and taking up too much space. ⚡ What Are Your Thoughts? Have you noticed 'category' data type using more memory in your projects? Share your experience!

Python Day 5

Today we warm up by completing Exercise 25. This is even more practice with functions and variables!

To run the program we call python in the terminal and import ex25 from there.

As I was working through calling the different functions in the terminal I realized that I missed a function - specifically the one that sorted a sentence. I called it and ended up getting a mess of individual letters. After bug hunting I found the issue to be that I called sort_words(sentence) instead of sort_words(words)

After fixing those issues I finished running through the function calls in the terminal and it went great!

Up next is Exercise 26! We are halfway through the book and it is time for a test. We are given broken code that we copy paste into a file. Our job is to fix it and get the program running! As I went through the program I left comments wherever I was fixing code. Below is my finished and fixed program.

And here is the output in the terminal:

Exercise 27 went over different booleans as well as a chart to memorize. The next practical was exercise 28 where you type in different statements then guess if they will be true or false. With my previous experience in programming I already knew a lot - the only thing that tripped me up was NOT OR booleans. Here's the output of the terminal!

Chugging right along to Exercise 29! ex29 introduced if statements. I already know lots about if statements from Javascript so this is more of a refresher than anything.

And then the output:

Exercise 30 introduces Else If statements.

And the output:

Exercise 31 combines everything that we've learned about If/Elif statements with the new concept of Nested statements. Using nested statements we are able to write a very simple Choose Your Own Adventure text game.

Here are a couple different runs I did with this program. My first try was not the best - I ended up having my mind turned into Jello!

My second run went better! I ran into a bear but I survived.

For the study drill it challenged me to write my own text game. I made a very simple one and got about halfway through where I want it to be.

That's it for today folks!
