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...

So the starting point is, again, to import that module, random. 让我们考虑一个简单的例子,其中列表中包含一组数字,我们希望从这些数字中随机统一选择一个。 Let’s think about a simple example where we have a set of numbers contained in a list,and we would like to pick one of those numbers...
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',...

but systematically benefits a lot from the preliminary pre-merge searches described under "Merge Memory" later. %sort approaches having a balanced merge at the end because the random selection of elements to replace is expected to produce an out-of-order element near the midpoint. \sort, /sort...
