Adding a breakpoint to Python for debugging

We can add breakpoint() to any blank line in python to catch the debugger there. Then, when we run our code, the debugger will stop at that line. We can navigate with:

  • n for next line
  • s step into function
  • c continue until next break point

We can also type python code into the debugger CLI to print vars or run other code.
