Replace Imports

[timothycrosley]

Currently, isort has functionality to enable adding imports and removing imports. It would be useful to add functionality to replace imports (adding only when removed).

Hi @timothycrosley! Do you mean something similar to these functionalities of CLI? https://github.com/PyCQA/isort#adding-an-import-to-multiple-files https://github.com/PyCQA/isort#removing-an-import-from-multiple-files Or do you mean something else? :)

@piotrgredowski exactly those! The project would be to add a third option to replace imports.

@timothycrosley I've started working on that. Can you assign it to me? And have two questions - should it be forbidden to use together:

1. adding imports with replacing imports,
2. removing imports with replacing imports?

If user can do both operations in same call - it will be harder to do :smiley: because what should be more important in that case?

If those constraints make it easier to create the initial implementation, I'm very comfortable with both being put in place. We'd just want to document it and make the error reporting as intuitive as possible.

Thanks!
