I just have one quick question. On the line where you have zip(*arr),
what is the * for? Is it like the pointer operator, such as with C? Or
is it exactly the pointer operator?
Otherwise, thank you for the example! This isn't homework, but I'm
working on something at work, and I was wondering how to properly
format the output from CSV files into another file. It's all a part of
an analyzer script for database tables, and the table wherein. Thank
you a bunch for the help!

I personally come from a background of using Java in an educational environment, so I'm pretty familiar with it. Going from a "pure" Object-Oriented language, where everything MUST be bundled into a class, and an Object is less of "a bit of data" and more of "a data structure that actually DOES something", was a little difficult. Just repeat this to yourself: Python ISN'T Java. Repeat it until the words start sounding funny to you. Then continue for another 10 minutes. It'll sink in. Anyhow... In Python, classes aren't necessarily treated as "things that do stuff" (though they can DEFINITELY act in that way!). Python classes are made to hold data. If you have something that you need to save for later, put it in a class and call it a day. If you only have a bunch of functions that are meant to process something, just put them into a module. You'll save yourself some time, you won't have to instantiate a class in order to call the functions, and you'll be happier overall.

Python Requests logging 401 immediately before 200
Hi everyone,
I'm using MarkLogic and have a Python script set up to check for documents
using Requests (http://docs.python-requests.org/en/latest/) and I have logging
included in the script.
I have logging set to the DEBUG level.
When I set the script to simple search and return the HTTP status code for
items it works, but when I look at what is generated by logging I see the
following for everything:
INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1):
localhost
DEBUG:requests.packages.urllib3.connectionpool:"GET
/v1/documents?uri=000248e4331d4db5856df8fd427b3cdb.xml HTTP/1.1" 401 211
DEBUG:requests.packages.urllib3.connectionpool:"GET
/v1/documents?uri=000248e4331d4db5856df8fd427b3cdb.xml HTTP/1.1" 200 18327
As you can see the 400 and the 200 are the same document (only 1 can exist in
ML with the same URI) and in MarkLogic's logs both are executed at the same
time.
When I search for a document using something like CURL for instance, I only get
the 200 status code which seems correct to me.
Is this something I should be concerned about and should fix or is it just the
log level I have set or something else I shouldn't worry about?
Thank you for your help!
Here's a snipped of my code in case it helps:
import requests
import logging
# initiate logging
log_path = os.path.join('my_log.log')
logging.basicConfig(filename=log_path,level=logging.DEBUG)
# make request
r =
requests.get('http://localhost:8004/v1/documents?uri=000248e4331d4db5856df8fd427b3cdb.xml',auth=HTTPDigestAuth('USER',
'PASSWORD'))

Shared script
I wrote a script that several different people on different machines need to run on a regular basis. When I first wrote it, it was in crisis mode, I got something out that was quick and dirty, very bare bones. Recently I had some more time, so I pushed most of the functions that the script uses into a module, because I use those functions on a pretty regular basis. My problem is this: The module is on MY machine in MY Python25 folder. I like it there, because like I said, I use the functions within it on a pretty regular basis. However, the other people who need to run the original script don't have the module. My quick fix was to throw the module into the shared folder, which works, but means everytime I have to update the module I have to update 2 different files, the one in my Python25 folder and the one in the shared network folder. Is there a better way to do this, short of asking everybody else to put the module in thir Python 25 folder (which would mean me e-mailing them to update the module, and then assuming that they did) ?!?

Executing a python script while it is running
Hi everybody, Here's my situation: I have a batch file that calls a python script. This batch file is triggered by an outside application when the application completes a task. The problem is that while the batch file (and pythons script) is running, the application will complete the next task, and try to call the batch file again (while it is already running) Hopefully that's not too confusing. I'm not sure what direction to go with this, any help or nudges in the RIGHT direction would be greatly appreciated. -- http://mail.python.org/mailman/listinfo/python-list
Re: Executing a python script while it is running
> A lot more information would be useful. What version of Python, and what > operating system environment? Exactly what would you like to happen when > the batch file is invoked a second time? I'm running Python 2.6.2 on Windows. I'm passing filenames to the batch files and I need all filenames to be processed. I can't have any fails. I'm working on logging any fails I do have so that I can maybe batch process at the end of the day. > 2) let them both run as separate processes This sounds like a good option, but I'm not totally sure on how to go about this? > 4) queue something to be processed when the first run finishes I had the same idea, but I believe it would involve having another python script run all day long, which wouldn't necessarily be a bad thing, but I'd like to explore other options as well. > What provisions does this existing application have for long-running batch > files? Seems the synchronization ought to happen there. Do you have any > constraints on how long your script might take, worst case? What if the > application finishes its tasks at a faster average rate than your script can > process them? The batch file is moving large video files. Duration probably ranges from 10 sec to 45 mins. On average, the application takes longer to process the files than it does the batch file/python script takes to copy them, but I'm concerned about the occasional time that the application finishes a small file right after finishing a large file.

Config files with different types
Hi all,
I've written a function that reads a specifically formatted text file
and spits out a dictionary. Here's an example:
config.txt:
Destination = C:/Destination
Overwrite = True
Here's my function that takes 1 argument (text file)
the_file = open(textfile,'r')
linelist = the_file.read().split('\n')
the_file.close()
configs = {}
for line in linelist:
try:
key,value = line.split('=')
key.strip()
value.strip()
key.lower()
value.lower()
configs[key] = value
except ValueError:
break
so I call this on my config file, and then I can refer back to any
config in my script like this:
shutil.move(your_file,configs['destination'])
which I like because it's very clear and readable.
So this works great for simple text config files. Here's how I want
to improve it:
I want to be able to look at the value and determine what type it
SHOULD be. Right now, configs['overwrite'] = 'true' (a string) when
it might be more useful as a boolean. Is there a quick way to do
this? I'd also like to able to read '1' as an in, '1.0' as a float,
etc...
I remember once I saw a script that took a string and tried int(),
float() wrapped in a try except, but I was wondering if there was a
more direct way.
Thanks in advance,
Zach

Mimicing an HTML form
Hi all,
I'm having alot of trouble automating the submitting of form. I have an
HTML page that works and it looks like this:
When I put valid values for the handling script an app ID, this page works.
Now I'm trying to turn this same functionality into a script. Here's my
code:
import urllib
import os
import urllib2
appID = *value here*
video = os.path.normpath(os.getcwd() + '/news.wmv')
title = 'News'
desc = 'Here is a sample News video'
uploader = *script here*
print "Encoding url..."
data = urllib.urlencode({"FileUploadedVideo": video,
"hdnADCID" : appID,
"txtTitle" : title,
"txtDescription": desc})
user_agent = 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'
headers = { 'User-Agent' : user_agent }
print "Calling url..."
req = urllib2.Request(uploader, data, headers)
response = urllib2.urlopen(req)
s = response.read()
response.close()
print "Writing results..."
result = open('result.html','w')
result.write(s)
result.close()
Does anybody have any suggestions? I keep on getting bad request, so I'm
assuming that the html page is passing something that my script is not. Is
there some way to scrape the POST request from the html form?

Dataframe iterating question : 3 ways of calling a row and column
I wouldn't say I'm a Python noob, but I wouldn't say I'm a Python expert either. I work in data science and use Pandas Dataframes a lot. My question is regarding the difference in calling out a specific row, column combination in a dataframe. I see 3 ways of doing this: (1) df.loc[row_ind, column_ind] (2) df.column_ind.loc[row_ind] (3) df[column_ind].loc[row_ind] where column_ind is the column name & row_ind is the named row index/row name in the dataframe. Can anyone enlighten me as to the differences between the above 3 methods of getting to the same cell in the dataframe? Are there speed differences? Is it simply a preference thing? Is there a PEP8 preferred way of doing this? Are there specific disadvantages to any of the methods? Thanks in advance. Zach -- https://mail.python.org/mailman/listinfo/python-list
