Python Debugging Tutorial

Welcome to our Python debugging tutorial! Debugging is an essential part of the development process. It helps you identify and fix issues in your code before they become problems for your users.

What is Debugging?

Debugging is the process of finding and fixing bugs in your code. A bug is an error in your code that causes it to behave unexpectedly.

Common Debugging Techniques

Print Statements: The simplest way to debug is to add print statements to your code to see what it's doing.
Breakpoints: Most IDEs allow you to set breakpoints in your code. When the code reaches a breakpoint, it will pause execution, allowing you to inspect the state of your program.
Logging: Logging is a more sophisticated way to track the execution of your program. You can log information at various levels (DEBUG, INFO, WARNING, ERROR, CRITICAL) to help you understand what's happening.

Debugging Tools

Pdb: Pdb is a Python debugger that can be used from the command line.
PyCharm: PyCharm is an IDE that includes a powerful debugger.
VS Code: VS Code is a lightweight editor with a built-in Python debugger.

Example

Here's a simple example of a Python script that has a bug:

def add(a, b):
    return a + b

result = add(5, 2)
print("The result is:", result)

To debug this script, you can set a breakpoint at the add function and see what's happening when you call it.
