I have a compressed file which I could uncompress on ubuntu command prompt using zlib-flate as below,
zlib-flate -uncompress < inputfile > outfile
Here inputfile is a compress file and outfile is the uncompressed version.
The compress file has a byte data.
I did not find the way to do the same using Python.
If the entire file fits in memory,
zlib can do exactly this in a very straight forward manner;
import zlib with open("input_file", "rb") as input_file: input_data = input_file.read() decompressed_data = zlib.decompress(input_data) with open("output_file", "wb") as output_file: output_file.write(decompressed_data)
If the file is too large to fit in memory, you may want to instead use
zlib.decompressobj() which can do streaming but isn’t quite as straight forward.
