Python Debugger

The Python module pdb defines an interactive source code debugger for Python programs. It supports the following features:

• setting breakpoints,
• single stepping at the source code line level,
• inspection of stack frames,
• source code listing, and
• evaluation of arbitrary Python code in the context of any stack frame.

You can use the pdb module to run your Python script interactive mode for debugging purpose, for example:

$ python3 -m pdb a1_template.py
>/home/rchan/ops435/a1/a1_template.py(2)<module>()
-> '''template for ops435 assignment 1 script
