Question

我正在为项目编写代码，我想要一些帮助。

当用户输入除男性或女性以外的其他内容时，会打印消息＆＃34;错误！请输入有效的性别！＆＃34;，但它不会重新运行输入声明，因此不会让他们选择性别。我想知道在用户收到错误消息后如何重新运行输入行。请让我知道如何使用Python 3.0做到这一点！

这是我的代码：

Gender = input("Your Gender (Male / Female):")
gender = Gender.lower()
if gender == "male":
  heorshe = "he"
  hisher = "his"
  himher = "him"
  himselfherself = "himself"
  HeShe = "He"
elif gender == "female":
  heorshe = "she"
  hisher = "her"
  himher = "her"
  himselfherself = "herself"
  HeShe = "He"
else:
  print("Error Please enter a valid gender!")
  print('\n')
  gender = False

我将非常感谢给予我任何帮助！

封装在while循环中，然后在找到您正在寻找的内容时突破它！

while(True):
  gender = input("Your Gender (Male / Female):").lower()
  if gender == "male":
    heorshe = "he"
    hisher = "his"
    himher = "him"
    himselfherself = "himself"
    HeShe = "He"
    break
  elif gender == "female":
    heorshe = "she"
    hisher = "her"
    himher = "her"
    himselfherself = "herself"
    HeShe = "He"
    break
  else:
    print("Error Please enter a valid gender!")
    print('\n')

如何循环if，elif else语句？
