If you want to perform shuffling as per your need, you can pass a custom function in the place of therandomargument, which will dictate theshuffle()function on how to randomize a list’s items. Example: – importrandom number_list = [7,14,21,28,35,42,49,56,63,70]# Original listpr...
如果想快速解决问题,那么是列表直接使用方法(1),如果是numpy.array()请使用方法(2)。 欲知区别和原因,请仔细看下面的分析: 首先需要区分两个random.shuffle()使用方法,一个是random中的,一个是numpy自带的。 (1)使用random带的random.shuffle() 使用方法: &nbs... ...
The random.shuffle() is a commonly used and recommended method to shuffle a list in Python. This shuffle method actually shuffles the element in place meaning it modifies the original list, hence, the ordering of the original elements in the List is lost. However, this may not be a proble...
random.shuffle(deck) # Sort by poker order and then by suit deck.sort(key=by_poker_order) deck.sort(key=by_suit) for k, g in groupby(deck, key=lambda c: c[-1]): print(k, list(g)) The code example creates a deck of cards. It groups the cards by suit and sorts them. ...

你可以把random.choice(someList)看成是someList[random.randint(0, len(someList) – 1]的一个简称。 random.shuffle()函数将对列表中的项目进行重新排序。这个函数原地修改列表,而不是返回一个新的列表。在交互式 Shell 中输入以下内容: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>> import rando...
