Python debugging techniques

To better debug a Python program, various techniques are available. We're going to look at four techniques for Python debugging:

• print() statement: This is the simplest way of knowing what's exactly happening so you can check what has been executed.
• logging: This is like a print statement but with more contextual information so you can understand it fully.
• pdb debugger: This is a commonly used debugging technique. The advantage of using pdb is that you can use pdb from the command line, within an interpreter, and within a program.
• IDE debugger: IDE has an integrated debugger. It allows developers to execute their code and then the developer can inspect while the program executes.
