# File test.py
def func_one():
return "one = 1"
def func_two():
return "two = 2"
if __name__ == '__main__':
import __main__
func = getattr(__main__, 'func_' + 'two')
print func()
import test
print getattr(test, 'func_' + 'one')()
which works, but importing yourself can be tricky. Try taking the "if
__name__" test out and running the script and see what happens.
This is probably a better way to solve your problem that doesn't rely on
the module importing itself:
def func_one():
return "one = 1"
def func_two():
return "two = 2"
funcs = {'one': func_one, 'two': func_two}
print funcs['one']
