Python Best Practices for Clean Code

Writing clean code is essential for maintainable and scalable applications. Here are some Python best practices.

Naming Conventions

Use descriptive names for variables, functions, and classes:

# Good
user_name = "John"
def calculate_total_price(items):
    pass

# Bad
un = "John"
def calc(x):
    pass

Function Design

Keep functions small and focused on a single responsibility:

# Good
def validate_email(email):
    return "@" in email and "." in email

def send_welcome_email(email):
    if validate_email(email):
        # Send email logic
        pass

# Bad
def process_user(email, name):
    if "@" in email and "." in email:
        # Send email logic
        pass

Conclusion

Following these practices will make your Python code more readable and maintainable.
