How can I refactor my code to improve readability?

Refactoring code involves restructuring it without changing its external behavior. You can improve readability by using meaningful variable names, breaking down large functions into smaller ones, and adding comments to explain complex logic.

Can you give me an example of a function that needs refactoring?

Sure! Here's a simple function that calculates the area of a rectangle but lacks clarity:

def calc(a, b):
    return a * b

Refactored, it could look like this:

def calculate_rectangle_area(width, height):
    """Calculate the area of a rectangle."
    return width * height

What kind of comments should I add?

You should add comments that explain the purpose of the function, the parameters it takes, and any complex logic within the function. For example:

def calculate_rectangle_area(width, height):
    """Calculate the area of a rectangle given its width and height."
    return width * height
