What Does The Google Styling Guide Say About Imports

Recently, I was reviewing Google’s Python style guide. Here’s what it says about imports.

When writing import statements, it is recommended to import the module instead of a function.

Quoting from the style guide:

Advantages:

• Namespace clarity: Importing the module makes the source of the function clear during invocation. For instance, my_module.my_function() tells that my_function is defined in my_module.

• Fewer import statements: If you intend to use many functions from a specific module, importing each function may not be feasible, as shown below:

Disadvantage:

• Explicitness: When you import a function instead of a module, it's immediately clear which functions you intend to use from the module.

Over to you: While the guideline is intended for Google's internal stuff, it may be applicable elsewhere. Yet, when would you still prefer importing functions over modules? Let me know :)
