# `tabnanny` — Detection of ambiguous indentation

Source code: Lib/tabnanny.py

For the time being this module is intended to be called as a script. However it is possible to import it into an IDE and use the function `check()` described below.

Nota

The API provided by this module is likely to change in future releases; such changes may not be backward compatible.

`tabnanny.``check`(file_or_dir)

  If file_or_dir is a directory and not a symbolic link, then recursively descend the directory tree named by file_or_dir, checking all `.py` files along the way. If file_or_dir is an ordinary Python source file, it is checked for whitespace related problems. The diagnostic messages are written to standard output using the `print()` function.

`tabnanny.``verbose`

  Flag indicating whether to print verbose messages. This is incremented by the `-v` option if called as a script.

`tabnanny.``filename_only`

  Flag indicating whether to print only the filenames of files containing whitespace related problems. This is set to true by the `-q` option if called as a script.

exception `tabnanny.``NannyNag`

  Raised by `process_tokens()` if detecting an ambiguous indent. Captured and handled in `check()`.

`tabnanny.``process_tokens`(tokens)

  This function is used by `check()` to process tokens generated by the `tokenize` module.
