Answer 1

Let's take look at what breakpoint() can do for you in 3.7+.

I have installed ipdb and pdbpp, which are both enhanced debuggers, via

pip install pdbpp
pip install ipdb

My test script, really doesn't do much, just calls breakpoint().

#test_188_breakpoint.py
myvars=dict(foo="bar")
print("before breakpoint()")
breakpoint()   #

There is a module called 'pdb' in python. At the top of your python script you do

import pdb
pdb.set_trace()

and you will enter into debugging mode. You can use 's' to step, 'n' to follow next line similar to what you would do with 'gdb' debugger.
