An example of execution a function in the background. The main execution will continue in the same flow without waiting for the background function to complete and the function set for background will continue its execution in the background

import time

def background(f):
    '''
    a threading decorator
    use @background above the function you want to run in the background
    '''
    def backgrnd_func(*a, **kw):
        threading.Thread(target=f, args=a, kwargs=kw).start()
    return backgrnd_func

    #This will print the count for every second
    for val in range(1, count+1):
        print("{} counts --> {}".format(fun_name, val))
        time.sleep(1)

# start the background function
# note that with the @background decorator
# background function executes simultaneously

print "My name is Amal. This is the main thread execution"
call_function("Background Function One", 6)

print "My name is Amal. The main thread reached here."
