我怎样才能使这个程序更短？

有必要在几列中显示随机字符。

import random

n = str()
n1 = str()
n2 = str()
n3 = str()
n4 = str()
n5 = str()
n6 = str()
n7 = str()
n8 = str()
n9 = str()
n10 = str()

while True:
    n = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n1 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n3 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n4 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n5 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n6 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n7 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n8 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n9 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    n10 = random.choice (["!", "№", "#", "$", "%", "@", "^", "&", "*"])
    print(n, n1, n2, n3, n4, n5, n6, n7, n8, n9, n10)

  1. 您可以将数组放入数组中，在while True中循环最多十个，您可以在其中使用局部变量，从数组中随机选择并输出

  2. Best Answer
    from random import choice
a = ["!", "№", "#", "$", "%", "@", "^", "&", "*"]
n = 10 # кол-во столбцов
while True:
    for i in range(n):
        print(choice(a), end="")
    print()

  3. import random

SYMBOLS = "!№#$%@^&*"
HOW_MANY = 11

random_symbols = random.choices(SYMBOLS, k=HOW_MANY)

print(random_symbols)

    解释：

    要从同一集合中重新选择一个随机字符，最好使用一个函数choices()（而不是choice()），该函数一次只返回（以列表的形式）您在参数中指定的字符k。

    笔记：

    当您不喜欢作为列表输出时（在方括号中），您可以循环输出列表项：

    for symbol in random_symbols:
    print(symbol, end=" ")

  4. 你的仔细重构会导致这个结果：

    import random

while True:
    choices = random.choices('!№#$%@^&*', k=10)
    print(*choices[:2], '', *choices[2:])

    $ python choices.py | head
! !  % $ % $ $ @ $ №
@ №  % * & ! @ * & !
# %  ! & @ % # № @ !
% *  ! * @ # * @ @ #
! &  % ! # № @ # * !
@ ^  & % @ @ & * № %
^ @  № № ^ № № ^ @ &
! @  ! @ № $ # @ $ №
№ %  ! ^ $ * ^ & * @
! ^  ^ % ^ № ! ! ! ^
Traceback (most recent call last):
  File "/home/sv/desk/stackoverflow/temp.py", line 5, in <module>
    print(*choices[:2], '', *choices[2:])
