As you've probably already noticed, it usually doesn't matter to Python (though it can become relevant in certain unusual circular-import cases). Most people will have some opinion about what constitutes good style, though. Opinions tend to look something like these (though details will vary): 1. All imports at the top of the module. 2. Standard library imports, then third-party imports, then local imports. 3. Sometimes the above types of imports are grouped with intervening blank lines. 4. Sometimes imports are alphabetized within those groups. > 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 : > > 1.

If you'd like to enforce an import order in your project, you can look at isort. [1] Carl [1] https://pypi.python.org/pypi/isort
