unindent does not match any outer indentation level

This error message typically occurs when there is a mismatch in the indentation levels in Python code.

Python relies on consistent indentation to define the scope of code blocks, such as loops, functions, and conditionals. If the indentation in a code block is not consistent, Python will raise an IndentationError.

The "unindent does not match any outer indentation level" error message usually indicates that there is an extra unindent (a decrease in the level of indentation) that does not correspond to any outer block. This can occur when mixing tabs and spaces for indentation, or when there are inconsistent use of spaces for indentation.

To fix this error, ensure that all lines in a code block are indented consistently using either tabs or spaces, but not both, and that the indentation levels match the expected scope of the block.
