Calling a function of a module by using its name (a string)

What is the best way to go call a function, given a string with the function’s name in a Python program. For example, let’s say that I have a module foo, and I have a string whose content is "bar". What is the best way to call

I need to get the return value of the function, which is why I don’t just use eval. I figured out how to do it by using eval to define a temp function that returns the result of that function call, but I’m hoping that there is a more elegant way to do this.
