zlib.error: Error -3 while decompressing: incorrect header check

Question

Hi, I have a gzip file and I am trying to read it via python as below:

import zlib

do = zlib.decompressobj(16+zlib.MAX_WBITS) fh = open('abc.gz', 'rb') cdata = fh.read() fh.close() data = do.decompress(cdata)

it throws : zlib.error: Error -3 while decompressing: incorrect header check

How can I overcome it.

Answer 1

Try the gzip module, code below is straight from the python docs.

import gzip
f = gzip.open('/home/joe/file.txt.gz', 'rb')
file_content = f.read()
f.close()
