process and spinning slash

[benz]

I am trying to fork and exec a child by python. Additionally, I am
attempting
to have a spinning slash while the child is running.

My code is as below:

import sys, os, time


def spin(delay):

  pattern=['-','\\','|','/','-','\\','|']

  while 1:
for i in pattern:
  sys.stdout.write(i + " ")
  sys.stdout.flush()
  sys.stdout.write("\b\b")
  time.sleep(delay)

pid = os.fork()

if pid == 0:
  os.execvp("du",("du","-shc","/"))
else:
  spin(0.05)


However, the spinner is kept spinning even the child process was ended.
Any idea ? Thanks!

I have rewrited my code as follow, but it still not working.

import os, sys


pid = os.fork()

if pid == 0:
  os.execvp("du",("du","-shc","/usr/share"))
else:
  while 1:
try:
  os.kill(pid,0)
  sys.stdout.write('running')
  sys.stdout.flush()
  sys.stdout.write('\b\b\b\b\b\b\b')
except OSError:
  print "child ended"
