Re: what gui designer is everyone using
I'm afraid that in my experience, doing things by hand has always ended up being quicker and simpler than relying on a GUI designer when it comes to building python GUI apps. That said, I've not tried any for the past few years so there may be a killer app out there that I've not tried :) But even then, it's likely that you'll still have to get your hands dirty in the code at some point. Also, it would help a little if you'd state which toolkit you were using (I'm assuming wxPython since you mention boa-constructor).

Re: which one do you prefer? python with C# or java?
Lisp and Clojure are functional languages. Learning one of those (or a similar language) will help by providing you with a fairly different perspective on how to approach programming problems. Personally I think learning Lisp or Clojure is good advice. However, if you're really adamant about going with Java or C# I'd probably go with Java. Not only can you play around on multiple platforms but should you decide to give Clojure a go in the future it'll come in handy :) (Clojure runs on the JVM so you can make use of Java libraries directly from it).

Re: which one do you prefer? python with C# or java?
My mistake about Lisp being purely functional (I have very little experience with common Lisp itself), though Clojure is. That doesn't change my point, to which you appear to agree, Lisp and Clojure teach folks a different way of approaching problems, which is always useful :) On Jun 10, 12:25 pm, Harald Hanche-Olsen wrote: > [becky_lewis ] > > > Lisp and Clojure are functional languages. > > No, they're not. > > But you can (and often will) do quite a bit of functional programming in > Lisp, as it lends itself quite naturally to that way of thinking. > > But in (Common) Lisp you also have CLOS, which is a rather different way > to do object oriented programming.

Re: ipython installed in virtualenv seems not to use virtualenv

Re: ipython installed in virtualenv seems not to use virtualenv

If both fail you get the message that you see. This might be a bit of a shot in the dark but could you try the path with and without a trailing '/' or '\'? I don't currently have a windows box available to test on and figure out why it would be detected as existing but not test true for either a file or directory.

My best guess is that something is preventing os.path.isdir from detecting the path as a directory under windows. I can't reproduce it on my Linux system but may have a working windows installation later. If I were you I'd fire up a python shell (execute python and get the >>> prompt), import os.path and manually try os.path.isdir(path_name) to try and find out what the actualy problem is. -- http://mail.python.org/mailman/listinfo/python-list

I've been hacking on the server for several days now (unrelated reasons) and have found that it's a little unforgiving when it comes to configuration errors. You need to be accessing the webdav server via the correct port (I think it's 8008 by default). If you're not doing this and something else is running on port 80 (which is where a webdav client will go to by default) then this would explain the 404 errors. -- http://mail.python.org/mailman/listinfo/python-list

Re: Multiplication error in python
I think you may be doing something wrong. If I run: >>> l = [1, 2, 3, 4, 5] >>> i = 0 >>> for a in l: ...i += 2 * a ... >>> i 30 The result is 30 as expected. Nowhere near the 155 that you are getting. :/ Again, could you state which version of python are you using (and what OS) so that we can run the code in the same environment as you.

Re: Can't install pycrypto
My best guess from the error and a quick look at the setup.py file is that during setup "chmod 0755 configure" is trying to run but failing. I'm guessing that you're on windows and don't actually have chmod, hence the error. The project on github looks active so you could go and ask for a windows friendly setup.py file and install using: python setup.py install or you could attempt to edit it yourself. I'd suggest asking for a windows friendly file on github as they will either give you a reason for it not being possible or will make the fix and everybody can benefit :) Hope that helps, Becky Lewis On Dec 5, 8:20 am, Alec Taylor wrote: > Good afternoon, > > Unfortunately my pycrpto install fails (tried with pip, easy_install > and pip -e git+) > > Error:http://pastebin.com/wjjfTZvd > > How do I get this working? > > Thanks for all suggestions, > > Alec Taylor -- http://mail.python.org/mailman/listinfo/python-list

Re: Python in web development
1) Python is absolutely fine for web development. It's just as good, if not better than PHP or Perl for this sort of work (that's my opinion anyway). 2) I've used Django quite extensively and it can certainly handle your requirements. You might want to have a look at Flask (http://flask.pocoo.org/) as it's not quite as heavy as Django so would possibly suit your needs a little better.
