mixed-indentation :: Pylint :: W0312

Error:

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

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

Description

Raised by pylint, when a mix of both spaces and tabs is used for indentation purpose. 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. This error is not fatal but considered a bad practice and could result in unexpected behavior.

Example(s)

Given sample of code describe basic divide function, it takes two arguments a and b. We have simple divided first argument with second and returned result. We have used spaces and tab both to represent  as single indentation

def divide(a, b):
        """
        function to take two arguments to divide first by second
        """
        try:
            result = a/b
        except ZeroDivisionError:
            result = 0
        return result

Solution(s)

PEP recommend four spaces to be used as indentation, So this could be resolved using standard four spaces for indentation.

Use Four spaces

Use four spaces for single indentation.

    def divide(a, b):
        """
        function to take two arguments to divide first by second
        """
        try:
            result = a/b
        except ZeroDivisionError:
            result = 0
        return result
