如何在列表中隨機打印變量

Question

例如：

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

像這樣：

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

阿卡行不通

我想要它打印出來的功能如：

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

Answer 1

抱歉，我無法確定是要程序隨機放置強盜還是要在兩種組合之間隨機選擇？ 嘗試了兩者中的第一個，但是如果您想稍后再說。 希望這可以幫助 ：）

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

Answer 2

我不太確定為什么要使用隨機函數，但是由於您知道要在哪里出現“ B”，因此可以。

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

喜歡

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

結果

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