I am trying to save the result of a function into a variable and print that variable on the screen, but when I print I see "none".   

How to repair this?

```
import time;

def hours():
    localtime =  time.localtime(time.time())
    print (localtime.tm_hour)

def minutes():
    localtime =  time.localtime(time.time()) 
    print (localtime.tm_min)

def seconds():
   localtime =  time.localtime(time.time())     
   print (localtime.tm_sec)

hours()
minutes()
seconds()

var = hours()
print(var)

```
