NameError:未定义名称"April"

Question

我知道这是愚蠢的,但我无法弄清楚为什么它不起作用.请帮忙.

def main():
    yourAge=getAge() #get subject's age
    yourWeight=getWeight() #get subject's weight 
    yourBirthMonth=getMonth() #get subject's birth month
    correctAnswers(getAge, getWeight, getMonth)

def getAge():
    yourAge=input('Enter your age. ')
    return yourAge

def getWeight():
    yourWeight=input('Enter your weight.')
    return yourWeight

def getMonth():
    yourBirthMonth=input('Enter your birth month. ')
    return yourBirthMonth

def correctAnswers(getAge, getWeight, getMonth):
    if getAge <= 25:
        print'Congratulations, age is less than 25.'

    if getWeight >= 128:
        print'Congratulations, weight is more than 128.'

    if getMonth == 'April':
        print'Congratulations, month is April.'

main()

使用raw_input(),而不是input(); 后者试图将文本输入解释为Python代码.

April在这种情况下,键入被解释为变量名称.你可以输入,"April"但最好不要input()在这里使用.
