Python incremente a number each second

How can I incremente a number each second? I was thinking to something like this.

import  threading

def printit():
    second = 1
    while threading.Timer(1, printit).start(): #for every second that pass.
        print(second)
        second += 1

printit()

There are a couple ways of doing this. The first as others have suggested is

import time

def print_second():
    second = 0
    while True:
        second += 1
        print(second)
        time.sleep(1)

The problem with this method is that it halts execution of the rest of the program (unless it is running in another thread). The other way allows you to perform other processes in the same loop while still incriminating the second counter and printing it out every second.

import time

def print_second_new():
    second = 0
    last_inc = time.time()
    while True:
        if time.time() >= last_inc + 1:
            second += 1
            print(second)
            last_inc = time.time()
 #       <other code to loop through>

I suggest a different method using time.sleep(1), the solution would be:

from time import sleep
def printit():
...     cpt = 1
...     while True:
...         print cpt
...         sleep(1)
...         cpt+=1

time.sleep(secs)

Suspend execution of the current thread for the given number of seconds.
