WebFeb 12, 2011 · 4. Python's math.factorial is not memoized, it is a simple for loop multiplying the values from 1 to your arg. If you need memoization, you need to do it explicitly. Here is a simple way to memoize using dictionary setdefault method. WebMar 4, 2024 · Now, let’s take a look at the function get_first which returns the first element of a list: def get_first (data): return data [0] if __name__ == '__main__': data = [1, 2, 9, 8, 3, 4, 7, 6, 5] print (get_first (data)) Independently of the input data size, it will always have the same running time since it only gets the first value from the list.

WebOct 25, 2014 · @BartoszKP and firegurafiku : math.factorial() is running at C speed so it's probably much faster than solutions that use Python loops. OTOH, factorial() grows very quickly: factorial(13) is too big to fit into an int, so the much slower long arithmetic must be used. firegurafiku's algorithm is better on that score than the simple factorial ...
