Diving deep on how imports work in Python

Submitted Nov 28, 2016

It just so happens python abstracts away the inner workings of import statement beautifully. But are we aware of how python behaves when it encounters an import statement for a module?

  • Better yet what is a module actually?
  • Packages anybody?
  • More than one import style? How to choose between them.
  • How would different import styles compare with each other.
  • Any Best practices when importing modules. What about that __init.py__ you saw the last time you read someone else’s code.

This talk will walk you through the above and more.
