带条件的错误输入行为

Question

如果用户没有键入m或f作为性别，我尝试将其重置。你知道吗

GenderSelect = input("Are they male or female?(m/f)\n")

os.system("clear")
gerror = 1
while gerror == 1:
    os.system("cls")
    print("Create a name for your new friend.\n" + NameCreate + "\nHow old are they?\n" + str(AgeSelect))
    input("Are they male or female?(m/f)\n")
    if (GenderSelect.lower() == "m"):
        print("Name: " + NameCreate + "\nAge: " + str(AgeSelect) + "\nGender: Male\n")
        gerror = 0
    if (GenderSelect.lower() == "f"):
        print("Name: " + NameCreate + "\nAge: " + str(AgeSelect) + "\nGender: Female\n")
        gerror = 0
    if (not(GenderSelect.lower() == "f" GenderSelect.lower() == "m")):
        gerror = 1

Confirm = input("Is this correct?\n")

if(Confirm.lower() == "y" or Confirm.lower() == "yes"):

当我键入f或m时，它会重置，但如果我键入其他内容，它不会重置

Answer 1

有几个问题：

1. 对于相互排斥的事物，使用elif而不是if
2. 在gerror块中的最后一个if语句中，两个条件之间需要一个or。或者直接用else。你知道吗

Answer 2

您的这部分代码：

if (GenderSelect.lower() == "f"):
    print("Name: " + NameCreate + "\nAge: " + str(AgeSelect) + "\nGender: Female\n")
    gerror = 0
if (not(GenderSelect.lower() == "f" GenderSelect.lower() == "m")):
    gerror = 1

应该是：

elif (GenderSelect.lower() == "f"):
    print("Name: " + NameCreate + "\nAge: " + str(AgeSelect) + "\nGender: Female\n")
    gerror = 0
else:
    gerror = 1
