Use therandom.choice()method: Thechoice()function takes one argument: the no-empty sequence like a list, tuple, string, or any iterable like range.Pass your list as an argument, and It will return a random element from it. Note: Thechoice()function returns a random element from the non...

To pick a random element from a non-empty sequence (like a list or a tuple), you can use random.choice(). There is also random.choices() for choosing multiple elements from a sequence with replacement (duplicates are possible):Python >>> items = ['one', 'two', 'three', 'four',...
