1. Indentation

Use 4 spaces per indentation level (no tabs).

def my_function():
    print("Hello, world!")

2. Maximum Line Length

Limit lines to 79 characters (72 for docstrings/comments).

# Good
message = "This is a short line."

# Bad (too long)
message = "This is a very long line that exceeds the recommended character limit of 79."

3. Blank Lines

• Use two blank lines to separate top-level functions and classes.
• Use one blank line inside functions to separate logic.

def first_function():
    print("First function")


def second_function():
    print("Second function")


class MyClass:
    
    def method_one(self):
        print("Method one")

    def method_two(self):
        print("Method two")

4. Imports
