Question

如果用户未为性别输入m或f，我试图将其重置。

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，但是如果我键入其他任何内容，它都不会重置。

Answer 1

几个问题：

对于相互排斥的事物，请使用elif而不是if
在gerror块中的最终if语句中，两个条件之间需要一个or。或只使用else。

Answer 2

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

应为：

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