I'm having trouble understanding how namespaces work in modules. I want to execute a module within the interpreter and then have values that are calculated persist so that other modules that get executed can retrieve them.
For example, consider the two simple modules below. The first method fails and I'm not sure exactly why. (Note: assume one instance of an interpreter. In my case a 3rd party software tool that starts an interpreter when it launches). Two alternate ways of running it: 1. (FAILS: RESULTS A = 0) Use the module "test" itself as the driver using the conditional statement if (__name__=="__main__"): test.py run2.py or, 2. (SUCCES: RESULTS A = 10) Use "run.py" as the driver. run.py _________test.py__________________ import sys,os A = 0 def getA(): global A return A def run(): global A A = 10 if (__name__=="__main__"): run() _________run.py__________________ import test test.run() print "A = " + str(test.getA()) _________run2.py__________________ import test print "A = " + str(test.getA()) -- Peter Bismuti Boeing Information Technology Renton, WA (425) 234-0873 W (425) 442-7775 C -- http://mail.python.org/mailman/listinfo/python-list
