Function for Factorial in Python
Easiest way is to use math.factorial (available in Python 2.6 and above): If you want/have to write it yourself, you can use an iterative approach: or a recursive approach: Note that the factorial function is only defined for positive integers so you should also check that n >= 0 and that isinstance(n, int). If it’s not, raise a ValueError or a TypeError respectively. math.factorial will take care of this for … Read more

(Or as they say “When in Rome, do as the Romans do.”) For you, that happens to correspond to unsigned int, but that might not … Read more
List of All Locales and Their Short Codes?
The importance of locales is that your environment/os can provide formatting functionality for all installed locales even if you don’t know about them when you write your application.
