I am trying to import a program that has a conditional execution
statement at the end so I can troubleshoot individual modules in the
main() program.
I'm not quite sure what you are doing here.
Can you give a bit more detail of how you are using this? How do you
import it?
Traceback (most recent call last):
File "<pyshell#0>", line 1, in -toplevel-
import rball
ImportError: No module named rball
Is rball in the import path? (sys.path)
(Also if I try to import with .py or .pyc)
Never include the .py or .pyc in an import
From the commandline interface, I can import the program, but __name__
is still "__main__" and I haven't successfully unit tested any of the
individual functions.
This bit confuses me. Which command line do you mean?
The OS or Python interpreter?
Also the only way you can test the functions is if name is main.
That's because the functions are all defined inside main().
That's a highly unusual pattern...
# rball.py
# textbook example of top-down design for Monte Carlo raquetball simulation
from random import random
This import is the only thing that happens if name is not main...
def main():
def printIntro():...
def getInputs():...
def simNGames(n, probA, probB):...
def simOneGame(probA, probB):...
def gameOver(a,b):...
def printSummary(winsA, winsB):...
> ...
>
if __name__ == "__main__": main()
Are you really sure that's what you want?
