Message

Found indentation with %ss instead of %ss

Found indentation with tabs instead of spaces
Found indentation with spaces instead of tabs

Description

Used when there are some mixed tabs and spaces in a module.

Explanation

Python interprets tabs and spaces differently, so consistent indentation is critical to the correct interpretation of blocks in Python syntax.

This warning is raised when a mix of both spaces and tabs is used in indentation—or more precisely, when an indent is detected that is not consistent with the indent-string option. By default, indent-string is set to four spaces, the style of indentation recommended in PEP 8.
