Question

我无法让程序重复循环直到mypot != 0。该程序的目的是询问用户放入底池的金额，并要求用户掷骰子直到mypot !=0

import random

mypot = int(input("Please enter the amount of money you want in the pot: "))
diceroll1  = random.randint(1, 7)
diceroll2 = random.randint(1, 7)
myrole = (diceroll1 + diceroll2)
while True:
    mypot > 0
if myrole == 7:
    print("Your roll was a 7 you eaerned press enter to roll again:  ", mypot + 4)
    break
elif  myrole != 0
    print("Sorry you did not roll a 7 press enter to roll again: ", mypot - 1)
    break
elif mypot != 0:
    print("Sorry you do not have no more money in your pot")
    break

更新：我无法让程序重复循环，直到mypot == 0

import random

mypot = int(input("Please enter the amount of money you want in the pot: "))
while mypot > 0:    # looping untill mypot <= 0
  dice_roll = random.randint(1, 7), random.randint(1, 7)  # rolling the dices
print(dice_roll[0], dice_roll[1])
myrole = sum(dice_roll)
if myrole == 7:
    mypot += 4    # without this you're not modifing the myrole value
    print("Your roll was a 7 you earned. Press enter to roll again:", mypot)
else:
    mypot -= 1
    print("Sorry you did not roll a 7. Press enter to roll again:", mypot)
input()   # waiting for the user to press Enter

print("Sorry, there's no more money in your pot.")

你的while循环非常奇怪：elif mypot != 0永远不会被打翻，因为之前的一个条件都是True，所以你的while循环也不是一个循环。

要解决此问题，您需要更改：

elif mypot != 0:
    print "Sorry you do not have no more money in your pot"
    break

使用：

if mypot != 0:
    print "Sorry you do not have no more money in your pot"
    break

把它放在其他ifs之前。

但您的代码似乎还有其他问题：

有：

mypot > 0

在while True之后，为什么不是：

while mypot > 0:
    # ...

同样myrole的值似乎没有在while循环中修改，那么while非循环在那里做什么？

DSM 建议您尝试将while非循环用作切换。

我认为你正在尝试做类似的事情：

import random

mypot = input("Please enter the amount of money you want in the pot: ")
# or as alternative:
#mypot = int(raw_input("Please enter the amount of money you want in the pot: "))
while mypot > 0:    # looping untill mypot <= 0
    dice_roll = random.randint(1, 7), random.randint(1, 7)  # rolling the dices
    print dice_roll[0], dice_roll[1]
    myrole = sum(dice_roll)
    if myrole == 7:
        mypot += 4    # without this you're not modifing the myrole value
        print "Your roll was a 7 you earned. Press enter to roll again:", mypot
    else:
        mypot -= 1
        print "Sorry you did not roll a 7. Press enter to roll again:", mypot
    raw_input()   # waiting for the user to press Enter

print "Sorry, there's no more money in your pot."

这有一些问题。首先，由于python使用所谓的语义空格，因此缩进很重要。所以你在哪里

while True:
 mypot > 0
if myrole == 7:
    print("Your roll was a 7 you eaerned press enter to roll again:  ", mypot + 4)
    break

它的读数为：正确时，评估（mypot＆gt; 0）。然后转到if语句。你的elifs也应该与if语句的缩进程度相同，并且你的frist elif之后你需要一个冒号。

无论如何，这可能不是最大的问题。在你的循环中，你没有任何改变。你需要将它移动到True：声明直到在diceroll1之上的ilne。在True之后的所有代码：将会反复执行，而在while循环中，myrole的值现在不会被重新分配。
