如何在lis中随机打印变量

Question

例如：

import random
Bandit="B"
List=["","","",""]

像这样：

import random
List=["","","",""]
List[i]='B'
for i in range(0,2):
    print(random.randint(List[i]))

Aka不起作用

我希望它打印出来的函数如下：

print["B","","B",""] or ["","B","","B"] and all the other combinations

Answer 1

抱歉，我无法确定您是希望程序随机放置bandit还是让它在这两种组合中随机选择？两个中的第一个，但如果你想后一个就说。希望这有帮助：）

import random
numb = random.randint(0,3)
bandit = "B"
list = ["","","",""]
list[numb] = bandit
print(list)

Answer 2

我不太清楚你为什么要用随机函数，但既然你知道B在哪里出现，你可以

List[i] = 'B'    # i is an integer, and it is where you want your thing to be

就像

List[0] = 'B'    # 0 is where a list starts 
List[2] = 'B'    

结果

['B','','B','']
