Python - 尝试运行代码时没有任何反应。我甚至没有收到错误

Question

我正在尝试使用Python创建一个小型投注应用程序，当我尝试运行程序时，没有任何事情发生。我正在使用IDLE。 这是我的代码：

def bet():
    #balance = 100
    x = 0
    with open("bal.txt", "r") as f:
        for l in f:
            bal = (sum([int(a) for a in l.split()]))
            while bal > 0:
                print ("Your balance is: " + str(balance) + " credits.")
                while x == 0:
                    print ("Enter the amount you would like to bet:")
                    bet = int(input())
                    if bet > bal:
                        x = 0
                    elif bet < 0:
                        x = 0
                    else:
                        x = 1
                print ("Pick a number between 1 and 20")
                num = int(input())

                convbal = bal - bet
                print ("Your bet is now locked in...")
                print (" ")
                print (" ")

                import random
                rannum = random.randint(1, 20)
                print ("Your guess was: " + str(num))
                print (" ")
                print ("The random number was: " + str(rannum))

                if rannum == num:
                    print ("WINNER")
                    bal = bal + (bet * 2)
                else:
                    print ("LOSER")
                    print ("")
                    print ("")

这是我在shell中收到的结果：

任何想法都会很棒，谢谢：）

Answer 1

代码所做的唯一事情就是定义一个名为bet的函数。您可以在IDLE shell中键入bet()来调用它，或者将bet()放在文件的底部（不缩进！）以自动调用它。

Answer 2

检查bal.txt可以打开，并且它至少有一行，其总和是＆gt;这里的事情是你的一个条件失败
