Python随机无重复 [英] Python Random's with no repeats

问题描述

这是我的代码，我试图用0-6之间的7个数字填充列表，没有重复，并且每次都随机排列.这是我的代码，但是我不断收到错误列表分配索引超出范围"，但是我看不到我的错误在哪里.这是我的代码:

Here is my code, im trying to fill a list with 7 numbers between 0-6 with no duplicates, and a random order every time. Here is my code but I keep getting an error "list assignment index out of range", I don't see where my error is though. Here is my code:

    import random
def generate():
    listA = []
    for x in range(0,6):
        listA[x] = random.sample(range(6), 1)
generate()
print(listA)

推荐答案

仅对 range 的结果进行 shuffle 会更有效.

It'd be more effective to just shuffle the result of range.

>>> from random import shuffle
>>>
>>> r = range(7)
>>> shuffle(r)
>>> r
[5, 3, 6, 4, 1, 0, 2]

请注意，在Python 3中，您必须将 r 明确转换为列表:

Note that in Python 3 you have to explicitly convert r to a list:

>>> r = list(range(7))
