Add Or Remove Imports

Adding an import to multiple files

isort makes it easy to add an import statement across multiple files, while being assured it's correctly placed.

To add an import to all files:

isort -a "from __future__ import print_function" *.py

To add an import only to files that already have imports:

isort -a "from __future__ import print_function" --append-only *.py

isort also makes it easy to remove an import from multiple files, without having to be concerned with how it was originally formatted.

From the command line:

isort --rm "os.system" *.py
