How can I use print statements for debugging in Python?

Using print statements is a simple yet effective way to debug your code. You can insert print statements at various points in your code to check the values of variables and the flow of execution.

Can you give me an example of how to do that?

Sure! For instance, if you have a function that calculates the sum of two numbers, you can add print statements to show the input values and the result like this:

def add(a, b):
    print(f'Adding {a} and {b}')
    return a + b

result = add(5, 3)
print(f'Result: {result}')

What if my code is too long? How do I know where to put the print statements?

In longer code, focus on areas where you suspect issues might arise, such as loops, conditionals, or before and after function calls. You can also print out variable values at critical points to trace the flow.
