Is it possible to load a script from it's text data, and not from a file?
I'm writing a scripting engine and need to run the scripts right from the

Hi Barry,
Obviously what you are trying to do is detect file locks. I am not

Sorry to diverge from the topic, but is there a reason you need to

Why? It's the same syntax as with functions:

You're talking about syntax from the bad old days

If not too archeological for your tastes, download
and boot a 1.5 and see what happens.
Less empirically, here're some key references:
http://www.python.org/doc/2.2.3/whatsnew/node9.html
http://www.python.org/
I've figured it out, it is default argument.
print y()
gives 13 as result.
It's a bit evil though.

the same thing it does in a function definition:

You need to subclass `urllib2.HTTPRedirectHandler`, override
`http_error_301` and `http_error_302` methods and throw
`urllib2.HTTPError` exception.
I'm reading this page:
http://www.ps.uni-sb.de/~duchier/python/continuations.html
and I've found a strange usage of lambda:
Now, CPS would transform the baz function above into:
def baz(x,y,c):
mul(2,x,lambda v,y=y,c=c: add(v,y,c))

Hello list,
I want to limit the download speed when using urllib2. In particular,
having several parallel downloads, I want to make sure that their total
speed doesn't exceed a maximum value.
I can't find a simple way to achieve this. After researching a can try
some things but I'm stuck on th
