autoflake

Remove unused imports and variables from Python code. More information: https://github.com/myint/autoflake.

• Remove unused variables from a single file and display the diff:

autoflake --remove-unused-variables path/to/file.py

• Remove unused imports from multiple files and display the diffs:

autoflake --remove-all-unused-imports path/to/file1.py path/to/file2.py ...

• Remove unused variables from a file, overwriting the file:

autoflake --remove-unused-variables --in-place path/to/file.py

• Remove unused variables recursively from all files in a directory, overwriting each file:

autoflake --remove-unused-variables --in-place --recursive path/to/directory
