What are the differences between these built-in Python data types: list, sequence and slice? As I see it, all three essentially represent what C++ and Java call array.
im having troubles with parsing a feed and getting the time. i am using dateutil.parser
from dateutil.parser import parse
print updated, parse(updated ), parse( updated ).utcoffset()
this should be a time in cali, output
2010-05-20T11:00:00.000-07:00 2010-05-20 11:00:00.000000-07:00 -1 day, 17:00:00
why is the offset -1 day 17 hours?
this is causing me issues when i try to do things with it
Suppose user enter this string at terminal
123 456 456 //then hit enter
How do I scan these three (could be more) numbers in different variables in python
Could be something like this:
for i in range(1,n)
m[i]=#WHAT FUNCTION SHOULD I PUT HERE
In c++ we can easily use cin>>m[i] inside above loop to scan the variables.
If i use input() or raw_input() , they would scan whole line in single variable.
Hi there,
I have a piece of text that gets handed to me like:
here is line one\n\nhere is line two\n\nhere is line three
What I would like to do is break this string up into three separate variables.
I'm not quite sure how one would go about accomplishing this in python.
Thanks for any help,

I have written a simple python module, it has this code:
_log = logging.getLogger("mymodule")
_started = False
def set_log_level(level):
_log.setLevel(level)
if not _started:
_hdlr = logging.FileHandler('mymodule.log')
When I call set_log_level() program fails because symbol _started is not found. It is normal because global _started is missing in the method. But my question is: symbol _log has the same visibility as _started, so why does this symbol can be found?

Hi,
In Python if I have 2 lists say:
l1 = ['a', 'b', 'c', 'd']
l2 = ['c', 'd', 'e']
is there a way to find out how many elements they have the same. In the case about it would be 2 (c and d)
I know I could just do a nested loop but is there not a built in function like in php with the array_intersect function
Thanks
Am surprised there's 3 different forms: RawConfigParser, SafeConfigParser and ConfigParser. I read the differences but why isn't everyone using SafeConfigParser, since it seems, well, safe? I can understand that in the case for Python 2 that the other two were kept for backward compatibility.
I have read about python sched (task schedular), it works like a cron.
but I have a question :
lets say if i schedule a function to ryn after every 2 hours and in the mean time my system gets shut down, then I again restart the system...did the schedular automatically starts and will run the function after 2 hours? or i have to start that again after shutting down the system?
did sched work like a deamon?
I'm trying to use python to determine if one (small) image is within another (large) image.
Any suggestions before I take myself completely down the wrong path?
Hey, here's a dumb question: how can I set an object property given its name in a string. I have a dictionary being passed to me and I wish to transfer its values into namesake properties using code like this:
for entry in src_dict:
if entry.startswith('can_'):
tgt_obj[entry] = src_dict_profile[entry]
I'm still a bit of a noob with Python so would appreciate some help.

Is it possible for my python web app to provide an option the for user to automatically send jobs to the locally connected printer? Or will the user always have to use the browser to manually print out everything.
I have a Python app that contains an object structure that the user can manipulate. What I want to do is allow the user to create a file declaring how the object structure should be created.
For example, I would like the user to be able to create the following file:
foo.bar.baz = true
x.y.z = 12
and for my app to then create that object tree automatically. What's the best way to do something like this?
I am iterating over an array in python:
for g in [ games[0:4] ]:
g.output()
Can I also initialise and increment an index in that for loop and pass it to g.output()?
such that g.output(2) results in:
Game 2 - name: Fruit Splat, text: "Splat fruits!", bitrate: 250000
it works fine on 64 bit machines but for some reason will not work on python 2.4.3 on a 32-bit instance.
i get the error
'utf8' codec can't decode bytes in position 76-79: invalid data
for the code
try:
str(sourceresult.sourcename).encode('utf8','replace')
except:
raise Exception( repr(sourceresult.sourcename ) )
it returns 'kazamidori blog\xf9'
i have modified my site.py file to make UTF8 the default encoding, but still doesnt seem to be working.
How can I parse text and find all instances of hyperlinks with a string? The hyperlink will not be in the html format of <a href="http://test.com">test</a> but just http://test.com
Secondly, I would like to then convert the original string and replace all instances of hyperlinks into clickable html hyperlinks.
I found an example in this thread:
Easiest way to convert a URL to a hyperlink in a C# string?
but was unable to reproduce it in python :(
Since input and raw_input() stop the program from running anymore, I want to use a subprocess to run this program...
while True: print raw_input()
and get its output.
This is what I have as my reading program:
import subprocess
process = subprocess.Popen('python subinput.py', stdout=subprocess.PIPE, stderr=subprocess.PIPE)
while True:
output=process.stdout.read(12)
if output=='' and process.poll()!=None:
break
if output!='':
sys.stdout.write(output)
sys.stdout.flush()
When I run this, the subprocess exits almost as fast as it started. How can I fix this?
Hello,
Is there a way to declare a string variable in python such that everything inside of it is automatically escaped, or has its literal character value? I'm NOT asking how to escape the quotes with slashes, that's obvious. What I'm asking for is a general purpose way for making EVERYTHING in a string literal so that I don't have to manually go through and escape everything for very large strings. Anyone know of a solution? Thanks!
Hi all,
I recently installed twython, a really sleek and awesome twitter API wrapper for Python. I installed it and it works fine from the interpreter, but when I try to import it via Eclipse, it says that twython is an invalid import.
How do I "tell" eclipse where twython is so that it will let me import and use it?
Thanks!
How do you end up running pypcap for python 2.6 on a mac? It seems that there hasn't been any new releases since 2.5 or am I just looking in the wrong places?
Hello everyone, i'm looking for a way in python to run an external binary and watch it's output for: "up to date" If "up to date" isn't returned i want to run the original command again, once "up to date" is displayed i would like to be able to run another script. So far I've figured out how to run the binary with options using subprocess but thats as far as I've gotten. Thanks!
Hi,
I need to construct an if statement from the data coming from the client as below:
conditions: condition1, condition2, condition3, condition4
logical operators: lo1, lo2, lo3 (Possible values: "and" "or")
Eg.
if condition1 lo1 condition2 lo3 condition4:
# Do something
I can think of eval/exec but not sure how safe they are! Any better approach or alternative?
Appreciate your responses :)
PS: Client-side: Flex, Server-side: Python, over internet
Thanks
I've always laughed to myself when I looked back at my VB6 days, "What modern language doesn't allow incrementing with double plus signs?":
number++
To my surprise I can't find anything about this in the Python docs. Must I really subject myself to number = number + 1? Doesn't people use the ++/-- notation?
:-(
What sort of mime type should I be using to email a .avi file from an automated python script? There are specific ones for audio/images, but not video afaik.
