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

任何人都可以幫助我添加一件事嗎?我想在losttwice <= 2(當我輸了1-2次)時得到50%的機率,因爲它是bet = startingbetbet = bet * 2,有50%的機率。Python:隨機分配兩個值中的一個

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

if random.random() > 0.5:(和頂部的import random)可能會有用。你應該能夠根據它來弄清楚。

進口隨機

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

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

Python有產生僞隨機性很大的模塊。文檔可以在here找到。如果您決定使用random.choice,代碼將如下所示:

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