Function call in Python

Check the following code:

def fibonacci(x):   
    if x < 2: return 1
    return (fibonacci(x-2) + fibonacci(x-1))
   
def factorial(x):
    if x < 2: return 1
    return (x * factorial(x-1))
   
def main():      
    funcs = [fibonacci, factorial]
    n = 10
    for i in range(len(funcs)):       
        print funcs[i](n)       
   
main()

Interesting part of the code is print funcs[i](n). Sometimes it is useful to call the function in this way.
