Can you give an example of a coding principle or standard you followed in your previous work?

One of the frequently applied coding principles in Python is following PEP 8 — the official style guide for code formatting. For example, using 4 spaces for indentation, naming variables in snake_case, and classes in PascalCase. This improves code readability and maintainability within a team.

Example:

class UserProfile:
    def __init__(self, user_name):
        self.user_name = user_name

    def display_name(self):
        print(f"User: {self.user_name}")

It is also important to write clear variable and function names, avoid overly long functions, and use comments where the logic is not obvious.
