What IDE are you using?


In the standard Python interactive interpreter, calling findHypot(3, 4) 
ought to print 5. The same applies in IDLE, or iPython. That's a 
convenience feature for interactive use.

But if you use IDLE to run the file as a script, using the Run Module 
command, then you're running in "batch mode", so to speak, and results 
aren't printed unless you explicitly use the print command.

So try changing your script to:

print(findHypot(3, 4))


for Python 3, or

print findHypot(3, 4)

for Python 2.
