Python：随机分配两个值中的一个

Question

if losttwice <= 2:
    bet = _________  # <- Here
elif losttwice <= 5:
    bet = bet * 2
else:
    bet = startingbet

任何人都可以帮我添加一件事吗？我希望losttwice <= 2（当我丢失1-2次时）有机会随机50％，因为它有bet = startingbet或bet = bet * 2基于50％的几率。

Answer 1

if random.random() > 0.5:（以及顶部的import random）可能很有用。你应该能够根据它来搞清楚。

Answer 2

if losttwice <= 2:
    bet = random.choice((startingbet, bet*2))

Answer 3

Python有一个很好的模块用于生成伪随机性。可以找到文档here。如果您决定使用random.choice，代码将如下所示：

from random import choice
if losttwice <= 2:
    bet = choice((startingbet, 2 * bet))
elif losttwice <= 5:
    bet = bet * 2
else:
    bet = startingbet

Answer 4

导入随机

if losttwice <= 2:
        if random.random() > 0.5:
            bet = startingbet
        else:
            bet = bet * 2
elif losttwice <= 5:
    bet = bet * 2
else:
    bet = startingbet

Answer 5

if losttwice <= 2:      
    bet = random.choice([staringbet, bet*2])
elif losttwice <= 5:
    bet = bet * 2
else:
  bet = startingbet
