How to debug ​

Debugging Python code is essential for every developer. One of the most straightforward yet effective ways to debug is by using print() statements.

Steps to Debug Using Print Statements ​

  1. Identify the Problem Area: Locate the section of your code where you suspect the problem might be.

  2. Insert print() Statements: Add print() statements before and after the suspected problematic code to print out variable values and flow control.

  3. Check the Results Output of your tests

  4. Analyze the Output: Look at the values printed in the results console to understand what's going wrong in your code. Adjust your code based on the findings and repeat as necessary.

Here’s an example of how to use print() for debugging:

python
def calculate_sum(a, b):
    print("calculate_sum called with arguments:", a, b) # Log function call
    sum_val = a + b
    print("Sum after addition:", sum_val) # Log sum calculation
    return sum_val

result = calculate_sum(5, 10)
print("Result of calculate_sum:", result) # Log the result
