i have a string variable which comes with function names, how do I call the function in Python?

Question

I have a string variable which comes with different function names, and I have a file which contains an often different set of functions which matchs the content of the string, how do I call that function in Python?

Example:

In File 1

def function1: ...
def function2: ...
def function3: ...

In File 2

functionname = "function2"

I need to call the function2 from the File1 from this file

@Tim Shell is evil as well. `myvar="myowntmpdir"; rm -rf ~/$myvra`. Or python's REPL... – khachik Nov 18 '10 at 12:28

name = 'function2'

assert re.match('^(?i)[_a-z][_a-z0-9]*$', name)

eval(name)()
