loading files to the interpreter

[Riku Voipio]

Hi, 
While coding, I have both the editor and the interpreter open at the 
same time. I end up testing a lot of the code by cut'n'pastiting them from 
the editor to the interpreter for test purposes. 

It would be a lot easier, if I could just type in the interpreter something
like 

>>load("~/programming/foo.py")

instead of copying the whole file (which can be very long). is there a way to 
load code in the "fly"?
