you can check the source of lzma module main compression and decompression algorithms were written in c. so obviously you will get faster performance. In [21]: import _lzma In [22]: _lzma.__file__ Out[22]: '/home/eightnoteight/.anaconda3/envs/snakes3.4.3/lib/python3.4/lib-dynload/_ lzma.cpython-34m.so' and regarding your problem, here's a simple example on how you can read line by line of your compressed 7z text file. import lzma with lzma.open('test.7z', 'w') as lf: lf.write(b'123\n'*1000) with lzma.open('test.7z', 'r') as lf: arr = list(lf) print(len(arr)) print(set(arr)) print(arr[0]) print(arr[0].decode('utf-8')) [gist] https://gist.github.com/38681cad88928b089abb later you can even extract that test.7z with 7z command line client with (7z x test.7z) -- https://mail.python.org/mailman/listinfo/python-list
