试图让答案重复[重复]

Question

如果输入的答案不正确，我会尝试重复问题。

answer = raw_input("Please enter the capital of Canada")
Times = 0

if answer == "Ottawa":
    print "good you made " + str(Times) + " attempts"
    print "you know Canadian Geography"
else:
    Times = Times + 1
    print "Please take another Canadian Geography course."

Answer 1

你会想要一个while 循环。

Times = 0

while True:
    answer = raw_input("Please enter the capital of Canada")

    if answer == "Ottawa":
        print "good you made " + str(Times) + " attempts"
        print "you know Canadian Geography"
    else:
        Times = Times + 1
        print "Please take another Canadian Geography course."

这将创建一个无限循环，因此您可能需要一些停止条件，例如用户回答错误 10 次。

Times = 0
StopTimes = 10

while True:
    answer = raw_input("Please enter the capital of Canada")

    if answer == "Ottawa":
        print "good you made " + str(Times) + " attempts"
        print "you know Canadian Geography"
    else:
        Times = Times + 1
        print "Please take another Canadian Geography course."

    if Times > StopTimes:
        break

Answer 2

与 Eric 的回答类似，但当他们做对时，这个循环就会中断。

注意 python3 使用 input 而不是 raw_input。

answer=raw_input("Please enter the capital of Canada:")

attempts=1
flag=True
while flag:
    if answer=="Ottawa":
        print("Good, you made %d attempts"%attempts)
        flag=False
    else:
        attempts += 1
        answer=raw_input("Please take another attempt, enter the capital of Canada:")
