Python equivalent of piping file output to gzip in Perl using a pipe

Question

I need to figure out how to write file output to a compressed file in Python, similar to the two-liner below:

open ZIPPED, \"| gzip -c > zipped.gz\";
print ZI         


        

Answer 1

Try something like this:

from subprocess import Popen, PIPE
f = open('zipped.gz', 'w')
pipe = Popen('gzip', stdin=PIPE, stdout=f)
pipe.communicate('Hello world\n')
f.close()
