This is the code I wrote but I doubt if its a live stream i am

I wanted some real time updates from my friends. The above code
fetches data from the 'latest' friends tweet and continues till 60th

someone.

Hi Harshad,
It depends on what you want those updates for? If it is a client then you
will have to stick with the methods you have described but if you are
writing and server end application then you can think of using streaming
api
with follow predicate. This will feed in to your application live updates
from the people you are following. But do not use streaming api if you
thinking of a client, as streaming API could be overwhelming for the client
side application.
Tweepy has code examples, which should help you with the sample code. Just
my 2 cents.

In the original twitter api, there was a method like

b=a.GetFriendsTimeline()
where we could get the friends time line after authentication. It used
to show maximum 20 tweets at a time.
Is there any similar method available in tweepy which will show live
updates? If yes, then what is the maximim number of tweets being
shown?
I would like to see a code snippet of the above method.

In addition, as any one who has done such trivial changes

site-packages.
It's a change for the Python 2.6 package, see

I know that this is possible by just calling the os commands 'mount/umount and mkfs' but this would imply to have to change sudoers to run the script as non-root. On Linux (I guess thats the target OS as you mentioned ext3) mounting could be done as non-root using FUSE or HAL (maybe using a frontend like gio or kio) if the system supports that, or with an appropriate fstab entry. Maybe HAL can configured to do mkfs but that has to be done very carefully to avoid security problems. Maybe you could use something like AppArmor, too. Most likely you get better answers by first asking in a Linux group how to do this things without root privileges and then come back to ask how to do it with Python.

really desirable.
Question 1. Where do I put the bulk of python scripts in a normal
linux environment?
Question 2. Should I use *.pyc rather then *.py files to speed up
executing as the user cannot write to /usr/bin or any other dir in the
system and everytime my app runs it will recompile it

A true (1/3) can only be expressed as a fraction. At the risk of being both boring and overly pedantic, that's not true. In base 3, the value in question is precisely representable in floating point: 0.1 As soon as you express it as a floating point - you are in a bit of trouble because that's impossible. It's not possible in base 2 or base 10. It's perfectly possible in base 9 (used by the Nenets of Northern Russia) base 12 (popular on planets where everybody has twelve toes) or base 60 (used by th Sumerians). [I don't know if any of those peoples used floating point in those bases -- I'm just pointing out that your prejudice towards base 10 notation is showing.] You can not express (1/3) as a floating point in Python any more than you can do it with pencil and paper. That's true assuming base 2 in Python and base 10 on paper. The base used by Python is pretty much etched in stone (silicon, to be precise). There used to be articles about people working on base-3 logic gates, but base-3 logic never made it out of the lab. However, you can pick any base you want when using paper and pencil. You can be precise and write 1/3 or you can surrender to arithmetic convenience and settle for the imprecise by writing 0.3, chopping it off at some arbitrary precision. Or you can write 0.1 3 :) Ahhh! But if I need to store the value 1/10 (decimal!), what kind of a precision pickle will I then find myself while working in base 3 ? How much better for precision if we just learn our fractions and stick to storing integer numerators alongside integer denominators in big 128 bit double registers ? Even the Nenets might become more computationally precise by such means ;-) And how does a human culture come to decide on base 9 arithmetic anyway? Just guessing: * Use one thumb to point at one of the other 9 fingers * Every finger (except for the thumb) has 3 segments (and links), each of which can easily divided in three part (upper, middle, lower or left middle, right for the links) making 9 points for each finger. Even base 60 makes more sense if you like it when a lot of divisions come out nice and even. You can count to 60 using two hands: Use the right thumb to point on one of the 12 segments of the remaining 4 fingers and on the left hand one finger for each dozen. Of course this is wasting resources as you can count to 1023 with your fingers. I never heard of a culture doing so, though.

Re: Type Hinting vs Type Checking and Preconditions
Tom Bradford [EMAIL PROTECTED] writes: Let me first say that I'm sure that this subject has come up before, and so forgive me for beating a dead horse. Secondly, let me say that Python's strength is its dynamic nature, and I don't believe that it should ever require a precondition scaffolding. With that said, I do believe that something like type hinting would be beneficial to the Python community, both for tool enablement and for disambiguous programming. Here is what I mean. The following function, though conventionally indicating that it will perform a multiplication, will yield standard Python behaviors if a string value is passed to it: def multiplyByTwo(value): return value * 2 Passing 14 to it will return 28, whereas passing 14 to it will return 1414. Granted, we know and accept that this is Python's behavior when you multiply two values, but because we don't (and shouldn't have to) know the inner workings of a function, we don't know that the types of the values that we pass into it may adversly affect that results that it yields. Now, on the other hand, if we were to introduce a purely optional type hint to the function prototype, such as follows: def multiplyByTwo(value:int): return value * 2 The python interpreter could do the work of casting the incoming parameter to an int (if it is not already) before it is multipled, resulting in the desired result or a typecasting error otherwise. Furthermore, it could do it more efficiently than a developer having to put conditional code at the beginning of traditionally typecasting functions. What's the advantage? Instead of multiplication may not do what I want with some classes you got casting to int may not do what I want with some classes. Passing a float now returns a much more counterintuitive result than passing a string in the old function. And it's not working anymore with classes which you can not cast to int but implement multiplication. In any case you have to document what exactly your function is doing and the user has to read this documentation. Florian -- Emacs doesn't crash!

However my biggest problem is a conceptual one. I just can't get my head around defining suitable classes, how they aquire data and communicate with each other. I'm hoping some of you python lamas out there might be able to share some of your wisdom on the subject. Just some thoughts about it: What I basically do is a lot of the following:: 1. get arbitrary numerical data (typically large data sets in columnar format or even via COM from other packages. I generally have to deal with one or more sets of X,Y data) You may create a class for each data format that reads that data and creates a set from it. 2. manipulate the data (scaling, least squares fitting, means, peaks, add/subtract one XY set from another etc) This methods may either manipulate youe set's data or create a new set with the data 3. plot data (original set, results of manipulation, scatterplot, histograms etc - I use matplotlib) I never useds matplotlib. Maybe it's usefull to have one or more classes covering the functions you need. 4. export data (print, csv, shelve) Again have a class for each output format. I have no problem writing bits of functional code to do any of the above. But for the life of me I can't see how I can hook them altogether in an OO based framework that I can build and extend (with more data formats, manipulations, GUI etc). When I think about what I should do I end up with a class XY that has a method for everything I want to do eg. class XY: def read_file def scale_data def plot_data def shelve_data But somehow that doesn't feel right, especially when I expect the number of methods will grow and grow, which would make the class very unwieldy. Even if that was a legitimate option, I don't understand conceptualy how I would, for example, plot two different XY objects on the same graph or add them together point by point. How do two different XY objects communicate Have a look at the IntervalSet module someone announced here some time before to get some ideas. and how do you deal with the thing that they must have in common (the plot screen for example). Create classes for this things. Then you may either pass XY to method of Thing or the Thing to a method of XY. Florian -- begin signature_virus Hi! I'm a signature virus.

Re: New WYSIWYG Python IDE in the works
McBooCzech [EMAIL PROTECTED] wrote: sorry for bothering you with my comment. From my point of view, the situation on the IDE (GUI??) development field for Python is really strange. Just try to imagine the same situation around the Python. Plenty of different approaches, versions, philosophies etc. Why people they really know the ways how to develop really good, prime and functional SW (I mean different developers of IDEs) do not do it together as a team (like in Python)? Why are there so many programming languages and people do not just concentrate on improving Fortran and Lisp? Why are there so many text editors and people do not just concentrate on improving vi and emacs? Different people have different needs and different ideas on how things should be done, so sometimes so want to have different software. Florian -- begin signature_virus Hi! I'm a signature virus.

Re: How to overcome automatic cyrillic-to-/hex convert
[EMAIL PROTECTED] [EMAIL PROTECTED] wrote: But when I enter some Bulgarian (actually cyrillic) text as a string, it seems that Python automatically converts it to '\x00..\x00 ' and once converted that way I can't get it back into its original look. The only way to get it right is using print : a = 'ÌÀÌÀ' # 'Mam' in Bulgarian print a 'ÌÀÌÀ' but a '\xcc\xe0\xec\xe0' Did you try the locale module? Florian -- begin signature_virus Hi!

Re: computer algebra packages
Rahul [EMAIL PROTECTED] wrote: Well is there an open source computer algebra system written in python or at least having a python interface? I know of 2 efforts: pythonica and pyginac...are there any others? Probably this is usable for you (I never used any of them): Package: mascyma Description: A user-friendly frontend for MAXIMA Mascyma is (trying to be) a user-friendly graphical frontend for the Computer Algebra System GNU MAXIMA. It is written in Python and provides two GUIs, one of which based on PyGTK, the other based on wxPython. Package: maxima Description: A fairly complete computer algebra system-- base system This system MAXIMA is a COMMON LISP implementation due to William F. Schelter, and is based on the original implementation of Macsyma at MIT, as distributed by the Department of Energy. I now have permission from DOE to make derivative copies, and in particular to distribute it under the GNU public license. . This package contains the main executables and base system files.
