Best Practices for Writing Clean Code

Writing clean code is essential for the long-term success of any software project. Here are some best practices to follow:

Use Descriptive Names

Choose names that clearly describe the purpose of variables, functions, and classes.

user_age = 30
is_logged_in = False

Keep Functions Focused

Each function should perform a single task. This makes your code easier to understand and maintain.

def calculate_total(price, tax):
    return price + tax

Write Comments

Comments help explain the purpose and logic of your code. Use them to clarify complex sections.

# Calculate the total price including tax
def calculate_total(price, tax):
    return price + tax

Follow Consistent Style

Consistent formatting improves readability. Use tools like Black or Pylint to enforce a coding style.

if is_logged_in:
    print("Welcome back!")
else:
    print("Please log in.")

By adhering to these best practices, you’ll write code that is easier to read, understand, and maintain.
