Python's approach to simple temperature conversion

This article illustrates a simple temperature conversion in python. Share with you for your reference. Specific analysis is as follows:

This is a simple python code, user conversion of different units of temperature, suitable for beginners reference

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
