The first thing to say is that python is not Perl so there will
be things Perl does more easily than Python and vice versa.

file1.read() works.
What do I do if I want line numbers ?
I found this code :

src = open('2.htm').read()
pattern = '([^<]+)' # or anything else
for m in re.finditer(pattern, src):
start = m.start()
lineno = src.count('\n', 0, start) +

Sorry its true, i made a mistake. Readlines is a list with all the lines
inside. I never used readlines (i usually use read), i just read about it on
the tutorial long time ago.
>>> f.readlines()
['This is the first line of the file.\n', 'Second line of the file\n'
Thanks for the help.

i believe that the following should work
file1 = open(fileO, 'r')
re.findall ('some_text', file1.read())
readlines returns a list with lists inside, where every list is a line of
the text. The read function returns the entire file as one string, so it
should work to what you are wanting to do.

The following works :
file1 = open (file0, "r")
re.findall ( 'some_text', file1.readline() )
But this doesn't :
re.findall ( 'some_text', file1.readlines() )
How do I use grep for a whole text file, not just a single string ?
