Re: Getting a stable virtual env

[JM]

This one should be in plain text, sorry guys I'm trying to get used to
this new mail address and client.

Hi ppl,

I'm trying to figure out the whole virtualenv story.
Right now I'm using it to creating an environment for our upcoming
debian upgrade to squeeze.

I'm doing some tests in our current distrib (python 2.5).
I have come to realize that a lot of packages in the version I'm
interested in are not available anymore on pypi. The pip installer
fails a lot.

Squeeze features python 2.7 so I'm pretty sure that everything will
work fine. I've actually tested it. The question is, how do I protect
myself from future package removal ?
Do I absolutely need to run a local pypi server (I've seen some python
package doing this), and mirror all the packages I'm interested in ?

cheers,

JM

Why this script can work?

[Jm lists]

Please help with this script:

class ShortInputException(Exception):
'''A user-defined exception class.'''
def __init__(self,length,atleast):
Exception.__init__(self)
self.length=length
self.atleast=atleast

try:
s=raw_input('Enter something --> ')
if len(s)<3:
raise ShortInputException(len(s),3)
# Other work can continue as usual here
except EOFError:
print '\nWhy did you do an EOF on me?'
except ShortInputException,x:
print 'ShortInputException: The input was of length %d, was
expecting at least %d' %(x.length,x.atleast)
else:
print 'No exception was raised.'


My questions are:

1) ShortInputException,x:   what's the 'x'? where is it coming?

2) The 'if' and 'else' are not in the same indent scope,why this can work?

Thanks in advance.

Re: Why this script can work?

[Jm lists]

Thanks for all the helps.
I'm not habitual for this usage of 'else',other languages seem don't
support this syntax.
i.g,writting the codes below by Perl would get an error:

# perl -le 'for $i  (1..10){print $i}  else{print "finished"}'
syntax error at -e line 1, near "}else"
Execution of -e aborted due to compilation errors.

Does eval has the same features as Perl's?

[Jm lists]

Hello members,

I want to know does the "eval" in python have the same features as in
Perl (capture errors)?

For example,in perl I can wrote:

$re = eval { 1 / 0 };

Though 1/0 is a fatal error but since it's in "eval" block so the perl
interpreter doesn't get exit.

Thanks again.

About getattr()

[Jm lists]

Hello,

Since I can write the statement like:

>>> print os.path.isdir.__doc__
Test whether a path is a directory

Why do I still need the getattr() func as below?

>>> print getattr(os.path,"isdir").__doc__
Test whether a path is a directory

Thanks!

tcp socket problem

[jm . carp]

I'm writing a tcp client that grabs data from a server at 32hz. But
the connection drops exactly one minute after it's opened. I can get
data from the server fine for the first 60s, and then the connection
goes dead. What's going on?
