text: Hi guys ,
  Im new at pythons . Hope you all can help me out here :
  Im trying to write a code which prints the elements from every list as a line . so If my lists are :
  l1 =
  l2 =
  l3 =
  the first two line of my output file should look like this :
  0000002 a 1
  0000003 b 2
  I tried it in this way but it didnt work :
  def listtofile():
  l1 =
  l2 =
  l3 =
  test_file = open('test3.txt', 'w')
  for i in range(0,8):
  s = l1+ '\t' + l2 + '\t' + l3
  test_file.write(s)
  test_file.readline()
  test_file.close()
  >>> listtofile()
  Traceback (most recent call last):
  File "C:\Program Files (x86)\Wing IDE 101 3.2\src\debug\tserver\_sandbox.py", line 1, in <module>
