Question

def main():
    userInput()
    calculate()

def userInput():
    print("Please put in the weight of your package:")
    a= input()
    weight= float(a)


def calculate():
    if weight <= 2:
        print('Your rate is $1.10')
    elif weight > 2 or weight <= 6:
        print('Your rate is $2.20')
    elif weight > 6 or weight <= 10:
        print('Your rate is $3.70')
    else:
        print('Your rate is $3.80')
main()

所以基本上我想知道如何在“计算”模块中使用“userInput”模块中的数据。我知道我有一个通过论证，但是（这让我疯了）因为我的生活我无法找到正确的方法来做到这一点。我理解参数的概念，但我无法在工作中的代码中实现它。感谢。

您可以将weight作为参数传递

def userInput():
    a= input("Please put in the weight of your package:")
    weight = None
    try:
        weight= float(a)
    except:
        userInput()
    return weight

def calculate(weight):
    if weight <= 2:
        print('Your rate is $1.10')
    elif weight > 2 and weight <= 6:
        print('Your rate is $2.20')
    elif weight > 6 and weight <= 10:
        print('Your rate is $3.70')
    else:
        print('Your rate is $3.80')

def main():
    weight = userInput()
    calculate(weight)

main()

作为旁白你可以用：

重写体重检查

if weight <= 2:
    print('Your rate is $1.10')
elif 2 < weight <= 6:
    print('Your rate is $2.20')
elif 6 < weight <= 10:
    print('Your rate is $3.70')
else:
    print('Your rate is $3.80')

注意使用“n＆lt; x＆lt; n +”符号

在shantanoo发表评论后更新：

我正在查看原始问题中的代码：

def calculate():
    if weight <= 2:
        print('Your rate is $1.10')
    elif weight > 2 or weight <= 6:
        print('Your rate is $2.20')
    elif weight > 6 or weight <= 10:
        print('Your rate is $3.70')
    else:
        print('Your rate is $3.80')

我意识到在两个elif行上，不需要进行第一次比较，代码可以重写为：

def calculate():
    if weight <= 2:
        print('Your rate is $1.10')
    elif weight <= 6:
        print('Your rate is $2.20')
    elif weight <= 10:
        print('Your rate is $3.70')
    else:
        print('Your rate is $3.80')
