我的函数没有在python中返回任何内容

Question

我为正在计算机科学课上工作的游戏定义了函数。

 def bidf(bid): #this card is going to repeat until they give a valid bid
     bid=float(input("What is your bid? "))
     if bid>pot:
         print("Invalid bid: You can't bid more than what is in the pot")
         bidf()
     elif bid>value:
         print("Invalid bid: You don't have that much")
         bidf()
     elif bid<0:
         print("You can not bid negative money")
         bidf()
     else:
         return float(bid)

每次我尝试使用bid变量都行不通例如，这段代码总是崩溃

if g=="y":
      bidf()
      if card(insidecard[0])==card(outsidecard[0]):
           z=input("Will the next card be higher or lower than the pair?(h/l): ")
           if card(insidecard[0])==14 and card(hand[0])==14:
                print("You quadruple your bid and lose $",bid)
                bid=bid*4
                value=value-bid
                pot=pot+bid

我正在尝试做的是获取要显示在打印语句中的出价，以及用于对其他变量进行数学运算的出价。

Answer 1

将所有对bidf()调用替换为return bidf() 。

Answer 2

当您在代码中调用bidf()时，您需要存储返回值。 因此，请执行以下操作：

if g=="y":
    bid = bidf()
