python function passed into another function as argument

I am new to pragramming and python. This is something like what I have.

 Def some_function():
     Print "stuff"

 Def another_function(x):
     running = True
     While running:
         x

another_function(some_function())

Why does it only print "stuff" the first time going through the loop?

I read some stuff that talked about late binding but not sure if that is what this is or how to fix it in my example.

You didn't pass the function, you called the function and passed its value. So it printed stuff before you ever got into the loop.

To refer to a function without calling it, you leave off the (). So it should be:

another_function(some_function);

Then in another_function, you have to call the function:

def another_function(x):
    running = True
    while running:
        x()
