Question

所以我正在做类似轮盘赌的循环，效果很好，除了它有时会停在“＃结束条件”部分（从底部向上10行），通常在2个循环之后停止。有什么了解输入（）保持其价值或类似的东西，即使没有一个变种还是我做错了什么？

# -*-coding:utf-8 -*

import os, math, random

user_number = 50
cash = 0
balance = 0

go_on = True

while go_on:
    # to_find init
    to_find = random.randrange(50)
    # bet and cash init
    if cash == 0:
        temp = input("How many cash do you bet ?\n")
        if int(temp) > 0:
            cash = int(temp)
    else:
        continue
    temp = input("Which number do you bet on (0 to 49) ?\n")
    if int(temp) >= 0 and int(temp) <= 49:
        user_number = int(temp)
    else:
        continue
    # cash modif
    if user_number == to_find:
        balance += cash * 3
        cash *= 4
        print("Woot we got a winner\nYou're now at,", cash, "$ !\nThe number was", to_find, "\n")
    elif user_number % 2 == to_find % 2:
        balance += math.ceil(cash / 2)
        cash = cash + math.ceil(cash / 2)
        print("Yay you got some money\nYou're now at", cash, "$ !\nThe number was", to_find, "\n")
    else:
        balance -= cash
        cash = 0
        print("Sometime you win... And sometime, you're back to 0 !\nThe number was", to_find, "\n")
    # end condition
    print("Your current balance is at", balance, "\n")
    if input("Want to try again ? Hit enter ! \nElse enter a number\n") == "":
        pass
    else:
        go_on = False

print("See you soon !")
if balance < 0:
    print("     And better luck next time !")

os.system("pause")

您有一个无限循环：如果在cash不为0的情况下触及循环的底部，则在下一次迭代中，您将触及{{1}的else部分}的条件，cash == 0会带您回到循环的开始，然后循环重复一遍。

看看您要做什么，我最好的猜测是您假设continue的工作方式像continue（不执行任何操作，等同于省略pass -部分）。

为了弄清楚这种情况是怎么回事，熟悉调试器可能是一项很好的投资，这将使您可以在任何行停止代码并调查每个本地代码的值。变量。周围有很多这样的东西，但是PyCharm Community就是一个很好的免费例子。

Python-如果输入未存储在变量中，输入是否保留值？
