How to debug functions in Python?

In Python, there are several commonly used methods for debugging functions.

1. You can use the print statement in functions to output the values of variables, allowing you to see how the variables change during the function’s execution.
2. In a function, you can use the assert statement to check if a certain condition is met. If it is not met, an AssertionError exception will be raised, helping us debug errors in the function.
3. The pdb module can be used to debug Python code by inserting breakpoints in functions, allowing for step-by-step execution and viewing variable values. By using the pdb.set_trace() function, breakpoints can be added within functions and variable values can be inspected and code can be executed interactively using the command line.
4. When using an IDE, you can utilize the built-in debugging tools for function debugging. Typically, the IDE will have a debug button that, when clicked, will insert breakpoints in the function and provide a debugging panel to view variable values and execute code.
5. Using third-party debuggers: in addition to pdb, there are other third-party debuggers available, such as PyCharm, VSCode, etc. These debugging tools offer more powerful and convenient debugging functions, allowing users to view variable values, execute code, set breakpoints, etc.
