def writeLineNumbers(filename):
    l = open(filename).readlines()
    l = [ l[i][:-1] + "\t#%s" % i for i in range(len(l)) ]
    open("%s.new" % filename).write("\n".join(l))

def stripLineNumbers(filename):
    l = open(filename).readlines()
    l = [ l[i][:l[i].rfind('#')] for i in range(len(l)) ]
    open("%s.new" % filename).write("\n".join(l))

howz that for obfuscated code ?? Anyway to put that open().readline() too in 
there ??

:)
Peace
