How do I find the current module name?
A module can find out its own module name by looking at the predefined global variable __name__. If this has the value ‘__main__’, the program is running as a script. Many modules that are usually used by importing them also provide a command-line interface or a self-test, and only execute this code after checking __name__:
def main(): print 'Running test...' # ... if __name__ == '__main__': main()
