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

复制代码 代码如下:

def c2f(t):
return (t9/5.0)+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 (t9/5.0)-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()

希望本文所述对大家的Python程序设计有所帮助。
