[Tutor] Shelve
I am running Python 2.6.4 under Windows Vista 32-bit Home Edition. When I run:
import shelve
test=shelve.open("myTest.fil")
I get a DCPermissionerror exception. I am an administrator on this machine (it
is my home PC). Python and Pythonw are both allowed exceptions to the Windows
firewall. I tried turning the Windows Firewall completely off, but that does
not help. Any ideas?

Re: [Tutor] Downloading S3 Logs
Mr. Mao, I am not a professional programmer. However, I do think that you want
to reduce the number of "things" that you have to do in loops that go through
the transaction (log entries in your case). Since you are converting to a
datetime, perhaps rather than doing a calculation, you should remove the
calculation and compare the datetime to yesterday (yesterday=now-1, whatever
the datetime needs to make it yesterday) in the "if" statement (I.e. change
"time_differnce < 1" to recordDate (<-make this instead of time_difference).
You can try changing things a bit to see if it speeds up. For example, if a
lot of messages are failing the "key.name.startswith("log/access_log")" test,
then maybe make a nested if, testing "key.name.startswith("log/access_log")"
before you actually test the date difference. Or, switch it around and test
the date first, the the "key.name.startswith("log/access_log")".
Sincerely,
Randy Raymond

Subject: [Tutor] Downloading S3 Logs
Hello,
I've written the below to get the previous day's logs from an Amazon S3 bucket.
#!/usr/bin/python
import time
from datetime import datetime
import boto
daily_s3_log = open("/tmp/s3logs", "w+")
now = datetime.now()
connection = boto.connect_s3()
bucket = connection.get_bucket("downloads.sekrit.co.uk")
todays_keys = []
for key in bucket:
time_difference = (now -
datetime(*time.strptime(key.last_modified.split(".")[0], "%Y-%m-%dT%H:
%M:%S")[0:6])).days
if time_difference < 1 and key.name.startswith("log/access_log"):
todays_keys.append(key)
for key in todays_keys:
key.get_file(daily_s3_log)
daily_s3_log.close()
This takes about 2 mins to download a day's logs (about 25M).
I'd appreciate any improvements or feedback on the above.
For example, would it make sense to make the first loop into a generator
function that yields the interesting keys? Also is there a cleaner way to do
the date comparison in Python 2.4?
Thanks,
Laomao

Re: [Tutor] Shelve
Ok, I see that is was the directory restriction that was the problem. Sorry
for the simple question.

Re: [Tutor] Running a dos program with python
I use wxPython, which allows a statement like:
wx.Execute('c:\shake91.exe "FLAC.txt" "a.txt" "b.txt"')

Hello all,
This is my first post to the Tutor@python.org mailing list. I am in the process
of switching from Matlab to Python and there is one task that I am having a
hard time doing and cannot find the answer on the web. I want to write a script
in python that will open up a windows dos program, send three inputs (file
names) into program and then run it. I know one way to open up the dos program
with os.system(r"c:\shake91.txt") but cannot do the rest.
Use the subprocess module:
http://docs.python.org/library/subprocess.html
untested, but should work:
subprocess.Popen([r'c:\shake91.txt', 'param1', 'paramN-1', 'paramN'])
if you want to communicate with the process you can add ,
stdout=subprocess.PIPE, stdin=subprocess.PIPE) to the function call.
Check the docs for more info.
HTH,
Wayne
Wayne,
It kindof works. I wrote
subprocess.Popen([r'c:\shake91.exe', 'FLAC.txt', 'a.txt', 'b.txt'])
The dos program pops up and if I hit the enter key three times then it runs.
How can I add these three "enters" into the script?
Thanks,
Richie
