i can define a function using the text editor provided by IDLE 3.0;
then i'd like to call this function from the python prompt
but when i try to do it, python warns me that function doesn't exist
of course if i define the function directly using the >>> prompt,
after that everything is fine
You need to save the file containing the function in a folder
in the Python search patyh. tHis is defined in sys.path:
import sys
print sys.path
Saving your file in any folder there will allow python to import
the file as a module.
Thus if you save it in
C:\MyProjects\Python\myFunction.py
and C:\MyProjects\Python is in your sys.path
You can then import your file with
import myFunction # notice no .py
And call your function foo() with
myFunction.foo()
You can add folders to sys.path either in a startup script or
using the PYTHONPATH environment variable. Make sure
its PYTHONPATH you create or modify not PATH, they
are very different!
