Introduction to debugging with python

introduction to debugging with python:

debugging is the process of identifying and fixing errors or bugs in your code. it is an essential skill for any programmer as it helps in ensuring that the code works as expected and produces the desired output. in python, there are several tools and techniques available for debugging code.

1. using print statements: one of the simplest ways to debug python code is by inserting print statements at various points in your code to check the values of variables and see the flow of execution.

example:

2. using python debugger (pdb): python comes with a built-in debugger called pdb which allows you to set breakpoints, inspect variables, and step through your code line by line.

example:

3. using ides with debugging support: integrated development environments (ides) like pycharm, visual studio code, and spyder provide powerful debugging tools that make it easier to debug python code. these ides offer features such as breakpoints, variable inspection, call stack visualization, and more.

4. handling exceptions: another important aspect of debugging is handling exceptions or errors that may occur during the execution of your code. using try-except blocks can help in catching and handling exceptions gracefully.

example:

by using these debugging techniques and tools, you can effectively troubleshoot and fix issues in your python code, leading to more reliable and efficient programs.
