Question

I’m working on a script, which will print a timer and was trying to reuse a function like this:

def timer(m,x):
    for i in range(1,x):
        sys.stdout.write('\r%s\b%d' % (m,i))
        sys.stdout.flush()
        sleep(1)
        sys.stdout.write('\r  \b')

Now, the part of the script, where I want a timer to be displayed is like this:

host_alive = "ping -c1 myServer"
cmdStat, cmdOut = commands.getstatusoutput(host_alive)

while True:
    if cmdStat != 0:
        (cmdStat,cmdOut) = commands.getstatusoutput(host_alive)
        print "Still NOT ready!!"
    else:
        break

How can I print a timer without specifying a range()? Is there any workaround?
Cheers!!

def timer(m):
    i = 0
    while True:
        sys.stdout.write('\r%s\b%d' % (m,i))
        sys.stdout.flush()
        sleep(1)
        sys.stdout.write('\r  \b')
        i = i + 1
