Can you explain what the PEP8 standard for Python code formatting is?

PEP8 is the official style guide for Python code, which helps make code readable and consistent.

Main recommendations of PEP8:

• Indents of 4 spaces, not tabs.
• Maximum line length of 79 characters.
• Variable and function names in lowercase with underscores (snake_case).
• Class names in CamelCase style.
• Use spaces around operators and after commas.
• Imports should be organized according to standards: standard libraries, third-party, local.
• Empty lines to separate functions and classes.

Following PEP8 makes code easier to maintain and collaborate on.
