python - Unzip my_file.zip pulled from s3 using boto -

-

i trying use boto open .zip file have in s3. trying work data directly, want avoid creating temporary files. 

in [201]: import stringio  in [202]: import boto  in [203]: conn = boto.connect_s3()  in [204]: my_bucket = conn.get_bucket('my_bucket')  in [205]: my_list = [ele ele in my_bucket.list('my_file.zip')]  in [206]: f = stringio.stringio()  in [207]: my_list[0].get_file(f)  in [208]: f.seek(0)

if file not zipped use:

my_content = my_list[0].get_contents_as_string()

but since zipped, getting garbage.

an answer question want (i borrowed bit of attempt it) using gzip, can't find using zip. tried using zipfilezipfile, read, extract , extractall methods don't seem want.

you should python module gzip :

https://docs.python.org/2/library/gzip.html

you should able stringio gzip. .

from boto.s3.connection import s3connection import gzip stringio import stringio  s3conn = s3connection() # assuming .boto has been setup bucket = s3conn.get_bucket('my_bucket') my_list = [gzip.gzipfile(fileobj=(stringio(ele.get_contents_as_string()))) ele in bucket.list()] #for readability pulled out item in my_list:     item.read()

for readability list comprehension should broken - followed original posting compare.

good luck!
