I am a bit tired of the standard answer, so let us try a funkier
approach! :)

# funk.py
ipow = 2
def xpow(xx): return xx**ipow

# xfunk.py
import inspect, funk
exec inspect.getsource(funk)
xx = 4.0
print xpow(xx)
ipow = 3
print xpow(xx)

And if you want trace information and be able to step through in a
debugger, you can use:

# funk.py
ipow = 2
def xpow(xx): 
    xx = xx / 0
    return xx**ipow

# xfunk.py
import inspect, funk
exec compile(inspect.getsource(funk), inspect.getabsfile(funk),
'exec')
xx = 4.0
print xpow(xx)
