python: read lines from compressed text files
Using gzip.GzipFile:
import gzipwith gzip.open('input.gz','rt') as f: for line in f: print('got line', line)Note: gzip.open(filename, mode) is an alias for gzip.GzipFile(filename, mode).I prefer the former, as it looks similar to with open(...) as f: used for opening uncompressed files.
You could use the standard gzip module in python. Just use:
gzip.open('myfile.gz')to open the file as any other file and read its lines.
