What are the consequences of using two spaces for indentation in Python?

In Python, indentation is critically important as it defines code blocks. The standard is to use 4 spaces per indentation level.

Using an indentation of two spaces will not cause a Python interpreter error if the indentation is consistent and aligned, but it violates PEP 8 — the official Python coding style. This can lead to:

• Reduced readability of the code for other developers.
• Problems when working with formatting tools and linters.
• Possible errors if different indentation styles are mixed in the project.

It is important to adhere to a consistent indentation style in the project, usually 4 spaces.
