How to call a python function by using a variable python

I needed to, in a programmatic way, determine the function name and then call the function.

Here's an example use case. I have a bunch of functions called, ["function1", "function2", "function3", "function4", etc] Then I have a function that takes a number as a param. Then should return the proper function.

class my\_awesome\_class():  
def function1(self, number):  
\# do something cool  

def function2(self, number):  
\# do something cool  


def test\_function(self, number, data):  
function\_string = ''.join(\['function',str(number)\])  
t = getattr(my\_awesome\_class(), function\_string)  
return t  
except AttributeError:  
print 'function not found "%s" (%s)' % (function\_string, data)
