Does the order in which the modules are placed in a file matters in Python?

Question

Iam on python 2.7 and linux .I need to know if we need to place the modules in a particular or it doesn't matter at all while writing the program.

For Example

import os
import shlex
import subprocess
import time
import sys
import logging
import plaftform.cluster
from util import run

def main():
 """ ---MAIN--- """

if __name__ == '__main__':
 main()

In the above example :

I am guessing may be the python modules like os , shlex etc come first and later the user defined modules like import plaftform.cluster etc

Sorry if my question sounds dump , I was running pep8 and don't see its bothered much about it

Answer 1

The order of the import statements is the order the modules will get loaded up. As a general rule this won't matter; when it comes to standard library modules, you can generally assume that you can put them in any order without it making any difference. It's common to order them in some aesthetically-pleasing way.

There is a broad convention that standard library modules get imported first, and modules that are part of the current project get imported afterwards. But even that doesn't usually matter very much.
