Python 内部 function 运行时复杂度

Question

Suppose I wrote a function to create another function, say like:

def g(x):
    #do stuff
    def h(y):
        return x*y
    return h

my_func = g(10)
for i in range(100):
    print(my_func(i))

In my for loop I am calling my_func a hundred times, however since I only call g once to create my_func I would expect that the #do stuff bit of my code will only run once at the beginning and not once every iteration of the loop.

Can anyone confirm that this is actually the case or will it run every single time inside the for loop? I couldn't find a satisfactory answer elsewhere.

Answer 1

Correct, if there was a line of code where #do stuff is, it would only run once in this example.

Tip: if you had replaced it with print("test") you could have checked this for yourself.
