Answer 1

Starting in Python 3.7, you can use the breakpoint() built-in function to enter the debugger:

foo()
breakpoint()  # drop into the debugger at this point
bar()

By default, breakpoint() will import pdb and call pdb.set_trace(). However, you can control debugging behavior via sys.breakpointhook() and use of the environment variable PYTHONBREAKPOINT.

See PEP 553 for more information.
