Question

大学生在这里和我正在使用python进行我的第一个真正的编码任务之一。主要问题是当它遇到问题1并且用户回答是或否时我得到错误。我认为因为使用了＆＃34;如果q1 ==＆＃34;是＆＃34;＆＃34;如果用户输入yes，则应打印下一行，或者如果用户输入no，则应继续下一个问题。任何帮助非常感谢请记住我的第一个编码课程。

def main():
    print("this is the common sense game.")
    n = eval(input("to begin please type 1: "))


    print("question 1: Do they have a fourth of July in England? ")
    q1 = eval(input("enter yes or no: "))
    if q1 == "yes": 
        print(" no there is a fourth of July in America GAME OVER.")

    print("question 2: are there three outs in an inning of baseball?")
    q2 = eval(input("enter yes or no: "))
    if q2 == "yes":
        print("no there are six GAME OVER")

    print("question 3: is it right to ignore a problem until it goes away? ")
    q3 = eval(input("enter yes or no: "))
    if q3 == "no":
        print("solve the problem the moment it occurs don't wait GAME OVER")
    else:
        print("Common sense is instinct, but enough of it is Genius" "YOU WIN")
    main()
main()

Answer 1

如果您使用的是Python 2，则使用raw_input，或者使用input代替{3}}而不是eval(input(。

这一行：

print("Common sense is instinct, but enough of it is Genius" "YOU WIN")

也有错误。

Answer 2

您需要将用户输入的结果转换为字符串。在您的代码中，if语句正在测试if q1 == "yes"，而不是if q1 == some variable named 'yes'。因此，您需要在问题中将eval()更改为str()：

def main():
    print("this is the common sense game.")
    n = input("to begin please type 1: ")


    print("question 1: Do they have a fourth of July in England? ")
    q1 = str(input("enter yes or no: "))
    if q1 == "yes": 
        print(" no there is a fourth of July in America GAME OVER.")

    print("question 2: are there three outs in an inning of baseball?")
    q2 = str(input("enter yes or no: "))
    if q2 == "yes":
        print("no there are six GAME OVER")

    print("question 3: is it right to ignore a problem until it goes away? ")
    q3 = str(input("enter yes or no: "))
    if q3 == "no":
        print("solve the problem the moment it occurs don't wait GAME OVER")
    else:
        print("Common sense is instinct, but enough of it is Genius" "YOU WIN")
    main()
main()
