Django - run a function every x seconds

I'm working on a Django app. I have an API endpoint, which if requested, must carry out a function that must be repeated a few times (until a certain condition is true). How I'm dealing with it right now is -

def shut_down(request): # Do some stuff while True: result = some_fn() if result: break time.sleep(2) return True

While I know that this is a terrible approach and that I shouldn't be blocking for 2 seconds, I can't figure out how to get around it. This works, after say a wait of 4 seconds. But I'd like something that keeps the loop running in the background, and stop once some_fn returns True. (Also, it is certain that some_fn will return True) EDIT - Reading Oz123's response gave me an idea which seems to work. Here's what I did -

def shut_down(params): # Do some stuff # Offload the blocking job to a new thread t = threading.Thread(target=some_fn, args=(id, ), kwargs={}) t.setDaemon(True) t.start() return Truedef some_fn(id): while True: # Do the job, get result in res # If the job is done, return. Or sleep the thread for 2 seconds before trying again. if res: return else: time.sleep(2)

This does the job for me. It's simple but I don't know how efficient multithreading is in conjunction with Django. If anyone can point out pitfalls of this, criticism is appreciated.

Learning Python Basics Week #3

*information from codeacademy.com*

Used https://www.quora.com/What-is-difference-between-a-parameter-and-a-variable-in-programming-languages-like-Python-read-details as a resource

Functions: 

If you’re trying to do an “if yes, say this” / “if no, say this” structure it as follows (s= type of shutdown): 

def shut_down(s): 

   if s == “yes”: 

      return “Shutting down”

    elif s == “no”: 

       return “Shutdown aborted”

    else: 

        return “Sorry”

Importing Modules: 

How to import the math module: type the following: import math

If you’re needing the square root, or any other specific math function, you can type the sequence as follows: 

       from math import sqrt

       print squat( ) *inside the parenthesis, put the number of your choice

Quick review of : argument, function, and parameters

Function is like a paragraph, argument is like the sentence, parameters are like words.

Function Breakdown: 

def________________( )      1. Define the name of the function with the (parameter mane, ex. num)

    if type ( ) == int or type( ) == float:     2. Type of if/or statement with int or float

        return abs( )                                   3. Give us the absolute value of ( )

    else:                                                   4. else, give us “Nope” 

         return “Nope” 

Using Python to Plan Things

To calculate costs per night: 

def hotel_cost(nights) 

    return 200 * nights 

City/Cost: Structure as follows: 

def plane_ride_cost(city)

    if city == “city name”: 

       return 200

    elif city == “city name”:

       return 450

To Add Costs: 

double(n) = double the return 

triple(n) = triple the return 

add(a, b) = gives sum of a + b

Lists: 

Definition! Type of datatype- here is where you can store a collection of information as a sequence 

Lists joins the group of datatypes we’ve already learned: strings, numbers, booleans

Format of a list: 

list_name = [item_1, item_2]

Index: 

Definition: gives item’s place on the list- helps you find an item on a list

Format: Use brackets! Remember, you begin lists at zero in python! 

Add things to a list: 

To get the number of things on a list, use: 

len(list_name)

Formatting a list example: 

grocery = [ ]

grocery.append(“apples”)

grocery.append(“salt”)

grocery.append(“carrots”)

grocery.append(“pizza”)

list_length = len(grocery)

print “There are %d items on the grocery” %(list_length)

print grocery

List Slicing: 

Definition: When you only want part of a list

create a list named: letters

the subsection is stored in a slice

ex. letters[1:3]

this means the 1 is included in the element, but the 3 is excluded.
