Ah, so you have a char* that has Python source code, and you want to
run a specific function in it.

For such questions, always ask yourself how you would achieve this
effect in pure Python, and then you'll see how to do it in C.

In Python, you could write

d = {}
exec sourcecode in d
func = d['SomeFunction']
func()

Now just do the same in C. Which of the four steps is unclear to you?
