Question

在我的Python游戏和骰子滚动游戏中，如果您猜对了数字，我会在其中工作，但是我正在尝试开发更高或更低的部分

但是在我的代码中，如果该值为3，并且您说得更高，它将表示您已经赢了。

示例#debug (5) Would you like to bet on higher or lower <h:l> <: l You won congrats! 但是我应该在这里输了而不是赢。

        elif user_nh == 'high':
        print(system_number)
        hiLo = str(input("Would you like to bet on higher or lower <h:l> <:   "))
        if hiLo == 'l' and system_number == 1 or system_number == 2 or system_number == 3:
            print("You won congrats")
            pa = str(input("Would you like to play again y/n :>     "))
            if pa == 'n':
                break
            if pa == 'y':
                continue
            else:
                print("You supplied a invalid response, quitting game.")
                break
        if hiLo == 'h' and system_number == 4 or system_number == 5 or system_number == 6:
            print('You won congrats!')
            pa = str(input("Would you like to play again y/n :>     "))
            if pa == 'n':
                break
            if pa == 'y':
                continue
            else:
                print("You supplied a invalid response, quitting game.")
                break

Answer 1

更好的是，由于您已经定义了较高和较低的数字，因此最好使用它们，如下所示：

第39行：

if hiLo == 'l' and system_number in lower:

第49行：

if hiLo == 'h' and system_number in higher:

Answer 2

像这样放入括号：

instance

但是您最好这样做：

if (hiLo == 'l') and (system_number == 1 or system_number == 2 or system_number == 3)

Answer 3

此行：

if hiLo == 'l' and system_number == 1 or system_number == 2 or system_number == 3:

正在评估类似这样的内容：

if   (hiLo == 'l' and system_number == 1): # Enter block
elif system_number == 2:                   # Enter block
elif system_number == 3:                   # Enter block
else:                                      # Don't enter block

因此hiLo == 'l'部分（当前）仅影响您的system_number == 1测试中的第一个。如果hiLo是2或3，则无论system_number的值如何，代码都会进入该块。

这是因为or运算符比and运算符具有higher precedence。

所以您可能想要类似的东西：

if hiLo == 'l' and (system_number == 1 or system_number == 2 or system_number == 3):

或

if hiLo == 'l' and system_number in [1,2,3]:

或

if hiLo == 'l' and (1 <= and system_number <= 3):

检查两个值是否相同
