python - 如何在调用后删除一个列表变量？

Question

States = 'alabama', 'alaska', 'arizona', 'arkansas'.....
randomState = random.randint(1, 50)
print(States[randomState])

我制作了一个脚本，可以从 50 个状态中随机选择一个状态，它可以工作，但我还想删除它调用的状态，因为它在调用的下一次迭代中不会重复使用相同的变量。

Answer 1

我们来了

import random

States = ['alabama', 'alaska', 'arizona', 'arkansas']
randomState = random.randint(0, len(States) - 1)
print(States.pop(randomState))

多次调用示例

import random

States = ['alabama', 'alaska', 'arizona', 'arkansas']

while States:
    randomState = random.randint(0, len(States) - 1)
    print('Removed random state: {}'.format(States.pop(randomState)))

输出

python test.py
Removed random state: alaska
Removed random state: alabama
Removed random state: arizona
Removed random state: arkansas
