python load gzip file

# Basic syntax:
import gzip

with gzip.open("/path/to/your/file.txt", 'rb') as file:
    for line in file:
        splitline = line.decode().split()

# Where:
#	- The gzip module allows you to read a gzip file.
#	- By default the data will be in byte form (e.g. b'line from your file');
#		however, you can convert it to a regular string (UTF-8) with decode().
