I am gonna ask the boss for PyCon, and I am pretty sure I am going to go regardless of job paying for it, at the very least for the conference.

That being said, this is discouraging.

m0nk3yz do you think it'll be better this year?

Yes, I do - I think a lot of us, myself included, largely agreed with Bruce. I think things will be changed quite a bit, and I know that the pycon organizers are watching out for this pitfall this year.

Also, I have two talks. You should go. I did a post this morning which may be the first of many

This is my first time using Python and I'm trying to design a web app. For now, I just want to create a simple "Hello World" type deal just to learn how Python works.

In PHP it's as simple as writing a hello.php file, echoing text and then uploading it to the server. Since I do not have command line access, just FTP access to our web server, is it even possible for me to create a site in Python? All the Python tutorials refer me to Django to build a site, and all the Django tutorials start with "run this on the command line". Are there any good online tutorials for degenerate PHP losers such as myself that are trying to learn this for the first time?

For learning probably get a 10MB account at http://www.alwaysdata.com/ it's free.

Stephen posted:

Yeah this won't really help. I already have the hosting and server, I just don't have command line access. Basically I've been given a project to do at my job that is easy to build and has a distant deadline and I thought it would be good to branch out my skills a bit by learning Python. Unfortunately I won't be able to use Python if I can't just build a site and then upload it a la PHP.

I guess I'm just a little confused on the whole process of how a web app is created using Python.

Your company is using a host to which you don't have shell access?

Correct. I'm just a lowly Web Developer. I can't be trusted with such toys. Up until now, we've simply used PHP to build all our pages so it hasn't been needed anyways.

Is there an easy way to randomize the retrieval of key, value pairs from a dict?

I have a paired list of {English : German} words, and I want to randomly pull an English word and its German translation. I know about d.keys(), but I'm not sure how to randomly select one from the result.

Tell your admins to set up django or mod_python for you, once that is done you can just drop files in a directory. mod_python can be set up to work just like php.

For testing you can run django localy on the local server. We'd be more than happy to help you in the django thread if you go that way.

Bleh mod_python. There's more problems with it that aren't even listed on that page, too. It would be better to use mod_wsgi, given the option. Its configuration is simpler, and it also supports adding actions to file types.

I know a couple of developers who have decided to give 09 a miss due to the poo poo that went on with the last pycon. Spending $5K+ to fly from australia to go to a conference on the other side of the earth only to have it wrecked by blatant spamming by vendors doesn't endear folks to the organisation of it all.

Nigel Tufnel posted:

Very very new to Python (learnt BASIC way back in the day). I've followed what I can of some tutorials but need answers to the following:

1. How can I embed a string within an outputted line?
Example:

code:

x='yes'
y='no'

print 'there is' X 'or' Y

Desired output: there is yes or there is no

quote:

What code do I need to use to get the strings x and y into my output?


2. How can I get outputs to split between lines?

Desired output:

This is line 1 with variable1
This is line 2 with variable2

something like:

code:

print 'this is line 1 with' variable1 \n\
print 'this is line 1 with' variable2

But that doesn't work because I cannae code for poo poo.

I know there was some discussion about contextmanagers earlier in the thread, as an FYI I just put the article from pymag up which gives a lot more information. It's only 2000 words or so, so I shouldn't get yelled at for it being too long. Here.

tl;dr


Seriously though, that was a great article makes me wonder if getting the Python Mag is worth it after all. (I assume you get a subscription for free for being a contributor? How is it?)

I also need to work through your other, longer recent reposts sometime; skipped them for now, not really due to the length but due to not caring as much about threading (yet).

unpack("8s","MAP01\0\0\0") gave me MAP01\0\0\0: it seems 8s is not handled as a zero-terminated string, but as a fixed-length blob. The best I could come up with was a wrapper around unpack:

code:

def _z(s):
  if type(s) == str:
    i = s.find('\0')
    if i != -1:
      s = s[:i]
  return s

def unpackz(format, data):
  return tuple(_z(s) for s in unpack(format, data))

So how come unpack doesn't support C-style zero-terminated strings, given that the whole point of its parent module seems to be to unpack C structs?

deimos posted:

It does support them, unpack determines the size of the resulting container. MAP01\0\0\0 is the correct output, try printing it and you'll see it prints correctly.

deimos posted:

code:

def _z(s):
    return s[:s.index('\x00')]

is a lot quicker than what you have you could even do the mundane s.rstrip("\x00")

RjY posted:

Maybe it's correct from the point of view of python, which can obviously handle zero bytes in strings, and so can treat them as arbitrary binary blobs - but in C (which is where this data is coming from) strings are terminated with a zero so the correct output should just be MAP01. In C it's extremely common to put a variable-length zero-terminated string into a fixed-size character array and I am surprised unpack won't do this for me. (Especially when it handles Pascal-style length-prefixed strings - compared to C, how common are they?)
All right but if I have more in the format string than 8s, or if the string I'm unpacking is 8 characters long and so doesn't have a \0 in it, it's just going to throw exceptions. (I am actually trying to unpack a struct { int offset, length; char name[8]; } using a format string of ii8s, but opted not to complicate the initial post with that)

Its printing the correct value. When you just call unpack from a prompt interactively it will show you null characters as well if they exist. What are you intending to do, toss out the trailing nulls?

I recommend any new to Python to start learning with version 2.6, as it is bridging the gap between Python 2 and 3.
