python温度转换代码_python实现简单温度转换的方法

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()
