I presume you mean that it is 'difficult to learn about compound 
statements and multiline simple statements with standard interactive 
python because one cannot edit lines already entered. True.

This is one of the great advantages of IDLE and any other IDE in which 
one keys in and can edit a complete multiline statement before 
submitting it to Python to run

It is also difficult to edit and rerun previously run multiline 
statements in the standard REPL when one must retrieve, edit, and enter 
previous lines one at a time.  Again, IDLE and anything similar makes 
this much easier by retrieving and allowing the editing and resubmission 
of complete multiline statements.

However, I don't see what this has to do with running system console 
commands in a Python shell.
