Dont bother with the debugger just yet.
For most python programmers, sticking a few print statements
(expressions in python 3) in adroitly is good enough.*
For now best if you concentrate on
1. What are the features of python -- the language
2. What are the standard data types and functions -- the libraries
3. How to use and jump between the two windows of your screenshot most
effectively. What you should and should not type in each etc
* One neat trick of using the print to debug.
Say you have a line like
nx.append("2")
and nx is not getting to be what you expect.
Change it to
nx.append("2"); print(nx)
Cleaning up the print after debugging is easier than if you use a
separate line like so
nx.append("2")
print(nx)
[I think I learnt this trick from Mark Lawrence]
