本文实例讲述了python实现简单温度转换的方法。分享给大家供大家参考。具体分析如下:

这是一段简单的python代码,用户转换不同单位的温度,适合初学者参考

def c2f(t):

    return (t*9/5.0)+32

def c2k(t):

    return t+273.15

def f2c(t):

    return (t-32)*5.0/9

def f2k(t):

    return (t+459.67)*5.0/9

def k2c(t):

    return t-273.15

def k2f(t):

    return (t*9/5.0)-459.67

def get_user_input():

    user_input = 0

    while type(user_input) != type(1.0):

        user_input = raw_input("Enter degrees to convert: ")

        try:

            user_input = float(user_input)

        except:

            print user_input + " is not a valid entry"

    return user_input

def main():

    menu = "\nTemperature Convertor\n\n"+\

        "1. Celsius to Fahrenheit\n"+\

        "2. Celsius to Kelvin\n"+\

        "3. Fahrenheit to Celsius\n"+\

        "4. Fahrenheit to Kelvin\n"+\

        "5. Kelvin to Celsius\n"+\

            "6. Kelvin to Fahrenheit\n"+\

        "7. Quit"

    user_input = 0

    while user_input != 7:

        print menu

        user_input = raw_input("Please enter a valid selection: ")

        try:

            user_input = int(user_input)

        except:

            print user_input + " is not a valid selction, please try again\n"

        if user_input == 1:

            t = get_user_input()

            print str(t) + " degree Celsius is " + str((c2f(t))) + " degree Fahrenheit"

        elif user_input == 2:

            t = get_user_input()

            print str(t) + " degree Celsius is " + str((c2k(t))) + " degree Kelvin"

        elif user_input == 3:

            t = get_user_input()

            print str(t) + " degree Fahrenheit is " + str((f2c(t))) + " degree Celsius"

        elif user_input == 4:

            t = get_user_input()

            print str(t) + " degree Fahrenheit is " + str((f2K(t))) + " degree Kelvin"

        elif user_input == 5:

            t = get_user_input()

            print str(t) + " degree Kelvin is " + str((k2c(t))) + " degree Celsius"

        elif user_input == 6:

            t = get_user_input()

            print str(t) + " degree Kelvin is " + str((k2f(t))) + " degree Fahrenheit"

        elif user_input == 7:

            quit()

        else:

            print str(user_input) + " is not a valid selection, please try again\n"

if __name__ == "__main__":

    main()
