#62337 — how to develop code using a mix of an existing python-program and console-commands

I have a python-program which I want to perform its task first, then
switch to
the python console to experiment with further commands, using what was
already
defined in the python-program.
I want this as an alternative for what I do now (but which is not very
efficient):
I start the python-console and then manually copy-paste line per line from
the program in the console, then try out possible continuation commands,
if however something goes wrong I have to redo the whole process.

any suggestions?
thanks in advance 
jean

Write the code to a file.  you can run it like:

python program_name.py

Go back to your text editor and do copy all (ctl-a, ctl-v) then open a
python console and paste it in

On the command line, python itself can take command line options,
including one that does exactly what you're looking for.

python -i script.py

That command will run script.py to its end, then drop you into the
interactive interpreter with the environment intact from running the
script.

Wow, Jerry, I didn't know that one.  Cool

An alternative to the excellent answer from Jerry Hill is to use the 
iPython %paste command.

This is effectively what Idle does when you run code in an editor 
window. You can interactive with the result in the Shell window. If 
there is a traceback, right click on a line in the traceback and select 
'goto' to go the the spot of the foul.

Excellent way to use/debug a scripting langugage. Use ipython, and then 
either

%run myfile.py

or

execfile('myfile.py')

You can do this multiple times, where the new definitions overwrite the 
old ones. In any case, ipython is much more friendly to use at the 
command prompt than plain python.

execfile is Python 2 only.
