循环直到给出正确答案

Question

您好，请有人帮忙。我对 Python 很陌生，我正在创建的东西需要帮助。我想打印六个语句，然后要求用户输入他们的答案。答案必须是ie。 S2、S10 等。如果不是真的希望它再次循环，直到给出正确的输入。

请看下面：

print("S0 = Initail Issue ")
print("S2 = Information Issue ")
print("S3 = Internal Review & Comment Issue ")
print("S4 = Suitable for Construction in DPP Stage only ")
print("S10 = Construction Issue")
print("CR = Construction Record (As Built)Issue\n")
Initial = "S0"
Information = "S2"
Review = "S3"
DPP = "S4"
Construction = "S10"
As_built = "CR"

Suitability = (input("Look above on the list of suitability is it?\n ").upper())
Suit = {"Initial", "Information", "Review", "DPP", "Construction", "As_built"}
while True:
    Suit = Suitability
    if Suit == Suitability:
        break
    else:
        print("is not the correct information! ")

    Suitability = (input("Look above on the list of suitability is it?\n ").upper())

Answer 1

print("S0 = Initial Issue ")
print("S2 = Information Issue ")
print("S3 = Internal Review & Comment Issue ")
print("S4 = Suitable for Construction in DPP Stage only ")
print("S10 = Construction Issue")
print("CR = Construction Record (As Built) Issue\n")
Initial = "S0"
Information = "S2"
Review = "S3"
DPP = "S4"
Construction = "S10"
As_built = "CR"

validOptions = [Initial, Information, Review, DPP, Construction, As_built]

while True:
    Suitability = (input("Look above on the list of suitability is it?\n ").upper())
    if Suitability in validOptions:
        break
    print("is not the correct information!")

print("You entered", Suitability)

我使用if item in container 语法来验证输入通过检查提供的输入是否在有效选项列表中。

我还重组了您的循环，以便您只需在代码中表达一次input 提示符。
