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

Question

Can someone tell me how can I Call a function in a string with function name in python program? E.x. Let's assume I have a module foo and a string with content "bar". So what can I do to call foo.bar()?

I know how to do this by using eval but I am looking for some another better method because I want a return value of the function and that's why I can't use it. I just want more efficient way to perform this task. 

Answer 1

You can use locals which returns a current local symbol table or you can use globals which returns a dictionary with global symbol table.

locals()["myfunction"]()

---

globals()["myfunction"]()

Answer 2

If you need to dynamically pick up the module, you can import it like as follows:

module = __import__('foo')

func = getattr(module, 'bar')

func()
