使用随机库在python3中交换list的元素

Question

使用随机库对列表进行排序，比方说数字列表_1。

导入python随机库的randint定义。

如何使用randint

Answer 1

import random
n=int(input())
list_1 = []
for i in range(n):
    list_1.append(int (input()))
list_2=[] 
while list_1:
    minimum = list_1[0]
    for x in list_1: 
        if x < minimum:
            minimum = x
    list_2.append(minimum)
    list_1.remove(minimum)    
sarr = [str(a) for a in list_2]
print(' '.join(sarr))

对于您问题中的第一个问题：

您不能使用random模块对列表进行排序，因为它是针对随机函数而不是排序的。但是，您可以使用Python的sorted()函数对列表进行排序。

作为完整程序

print(sorted(eval(input())))

说明

print(                          Print out ...
      sorted(                   The sorted version of ...
             eval(              The evaluated version of ...
                  input()       The input
             )
      )
)
