How do you find and fix bugs in your code?

To find and fix bugs in the code, I use several approaches:

• Logging: I add detailed logs to understand at which stage the problem occurs.
• Debugger: I run the code in debug mode (for example, using pdb in Python) to step through execution and check variable values.
• Unit tests: I write tests that help identify errors early and verify the correctness of functions.
• Exception analysis: I carefully read error messages and stack traces to understand the cause of the failure.

Example of using pdb for debugging in Python:

import pdb

def divide(a, b):
    pdb.set_trace()  # Breakpoint
    return a / b

print(divide(10, 0))  # This will raise a ZeroDivisionError
