Python format css file method _python

The example in this article describes the way Python formats CSS files. Share to everyone for your reference. The implementation methods are as follows:

Import string, sys
import Re, Stringio
tab=4
def format (ss):
  f = open (ss, "R")
  data = F.read ()
  F . Close ()
  Dlen = len (data)
  i = 0
  buf = Stringio.stringio ()
  start = 0 while
  i < dlen:
    if data[ I] = = = = ' {':
      buf.write (data[start:i] + ' {')
      i = i + 1
      start = i
    elif data[i] = = = ': Last
      = Strin G.strip (data[start:i])
      if last:
        buf.write (' *tab + last + '; ')
      Buf.write ('} ')
      i = i + 1
      start = i
    elif data[i] = = '; ': line
      = String.strip (data[start:i))
      buf. Write (' *tab + line + '; '
      i = i + 1
      start = i
    else:
      i = i + 1
  buf.write (data[start:i+1]) return
  buf.getvalue () 
  if __name__ = = ' __main__ ':
  If Len (sys.argv) = = 1:
    print ' usage:cssformat.py filename '
    sys.exit ()
  ret = format (sys.argv[1])
  PRINT ret
