Outputting to a text file

How to print the following code to a .txt file

y = '10.1.1.' # /24 network, 
for x in range(255):
    x += 1
    print y + str(x) # not happy that it's in string, but how to print it into a.txt

There's copy paste, but would rather try something more interesting.

From stackoverflow

• f = open('myfile.txt', 'w')
  for x in range(255):
      ip = "10.1.1.%s\n" % str(x)
      f.write(ip)
  f.close()
  

  mhawke : This won't give the result required: write() does not add newlines, so you end up with a single line of output.

  Fred Larson : @mhawke: There's a newline character in ip, though.

  mhawke : @Fred: yes, you're right. sorry about that. Anyway, there *is* a problem with the range(255) being zero-based.

• scriptname.py >> output.txt

  Jeremy Cantrell : I think this is the more flexible solution.

• What is the x += 1 for? It seems to be a workaround for range(255) being 0 based - which gives the sequence 0,1,2...254.

  range(1,256) will better give you what you want.

  An alternative to other answers:

  NETWORK = '10.1.1'
  f = open('outfile.txt', 'w')
  try:
      for machine in range(1,256):
          print >> f, "%s.%s" % (NETWORK, machine)
  finally:
      f.close()
  

• In Python 3, you can use the print function's keyword argument called file. "a" means "append."

  f = open("network.txt", "a")
  for i in range(1, 256):
      print("10.1.1." + str(i), file=f)
  f.close()
