the pattern

<meta content(+.?)refresh">

the string big tried different approaches neither works. don't save string in txt file.

the script tried didn't work.

#try 1 import re re.findall("<meta content(+.?)refresh">",html) #try 2 matching = [s s in html if "<meta content(+.?)refresh">" in s]

the question comment was: 'i grab out section of string start "meta content" , finishes "refresh">".'

i split lines because way ^ matches start of each line, not whole string. used ^ match start , $ match end. in fact these not necessary since < , > sufficient. note double quote escaped slash character before it.

another key point: it's not +.? .*? work grab characters in middle of string.

>>> import re >>> line in html.splitlines(): ... m = re.match("^<meta content(.*?)refresh\"/>$", line) ... if m: ... print(m.group(0)) ... <meta content="420" http-equiv="refresh"/>
