Interview question

What is PEP 8 and why does it matter? PEP 8 क्या है और यह क्यों important है?

Answer

PEP 8 is Python's official style guide, defining conventions for naming, indentation, line length, imports, and formatting to keep code consistent and readable across projects and teams.

Rule	Convention
Indentation	4 spaces, no tabs
Line length	Max 79 characters (some teams use 88-120)
Variable/function names	snake_case
Class names	PascalCase (CapWords)
Constants	UPPER_SNAKE_CASE

# PEP 8 compliant
MAX_RETRIES = 5

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

    def get_display_name(self):
        return self.user_name.title()

# Not PEP 8 compliant
class useraccount:
    def __init__(self,UserName):
        self.UserName=UserName

Tools like flake8, pylint, and black help automatically check or enforce PEP 8 compliance.
