Debugging

Principles

Debugging is a skill among many senior developers.

Linting = allows us to detect issues as one codes. IDE’s like PyCharm or VSCode help with this.

IDE/Editor = choosing a specific editor can help in the process for debugging.

Recognizing Errors = knowing the difference between a SyntaxError and a TypeError.

PDB

Python Debugger allows us to interact with the code.

            `import pdb

            def add(num1, num2):
                pdb.set_trace()
                return num1 + num2
                
            add(4, 'hjsdgfuh')`

pdb is a way to simulate the execution of your code in the command line. It’s a way of testing your code within the command line without actually running the code in the command line.

The computer will pause the code after the line pdb.set_trace() and you can view or manipulate it.
