[SOLVED] Find last occurence of pattern in text file?

[Winfried]

Hello,

In a multiline text file, I need to find the last occurence of a pattern, ie. the Python equivalent of "tail".

None of the following works:

import re

INPUTFILE = "log.txt" 

with open(INPUTFILE) as reader:
    content = reader.read()

#====================
#very slow, even on 130KB file
p = re.compile("(?s:.*)^Some pattern.+$")
m = p.search(content)
if m.group(0):
	print(m.group(0))

#====================
#IndexError: list index out of range
p = re.compile("^Some pattern.+$")
m = p.findall(content)[-1]
if m.group(0):
	print(m.group(0))

#====================
#AttributeError: 'NoneType' object has no attribute 'group'
p = re.compile("^Some pattern.+$")
for line in content:
	m = p.search(line)
	if m.group(0):
		print(m.group(0))

#====================
#AttributeError: 'str' object has no attribute 'readlines'
for line in content.readlines():
	m = p.search(line)
	if m.group(0):
		print(m.group(0))

Anyone knows?

Thank you.
