You can use gzip and shutil libraries of Python to compress a file. Here is an example.

I am compressing my input text file 'inp.txt'

import gzip
import shutil
fin = open('data/inp.txt', 'r')
with gzip.open('data/inp.txt.gz', 'wb') as fout:
    shutil.copyfileobj(fin, fout)

To unzip and read the content of the gzipped file, you can use the following code:

with gzip.open('data/inp.txt.gz', 'rb') as f:
    for line in f:
