What is the coding style used in Google projects?

The coding style in Google projects for Python is based on PEP 8 recommendations, but with some internal additions and standards that ensure readability, consistency, and scalability of the code. Key points:

• Use of 2 spaces for indentation (instead of 4 in standard PEP 8).
• Maximum line length — 80 characters.
• Clear and descriptive variable and function names.
• Documenting functions with docstrings in Google style format.
• Avoiding excessive nesting and complex structures.

Example of a Google style docstring:

 def add_numbers(a, b):
     """Adds two numbers.

     Args:
         a (int): The first number.
         b (int): The second number.

     Returns:
         int: The sum of numbers a and b.
     """
     return a + b

Thus, Google's coding style aims to maintain code cleanliness and readability in large teams.
