I want to do something like the following (let's pretend that this is
in file 'driver.py'):
#!/bin/env python
import sys
def foo():
print 'foo'
def bar(arg):
print 'bar with %r' % arg
def main():
getattr(driver, sys.argv[1])(*sys.argv[2:])
if __name__=='__main__':
main()
Essentially what I'm trying to get at here is dynamic function
redirection, like a generic dispatch script. I could call this as
python driver.py foo
or
python driver.py bar 15
and at any time later I can add new functions to driver.py without
having to update a dispatch dict or what-have-you.
The problem is, 'driver' doesn't exist in main() line 1. If I 'import
driver' from the command line, then getattr(driver, ...) works, but
it's not bound here.
Is there any way around this? Can I somehow scope the 'current
module' and give getattr(...) an object that will (at run time) have
the appropriate bindings?
Thanks in advance for all advice!
Mike
