Actually, it can be. a = func() b, c = a[:1], a[1:] vs b, *c = func() The first version leads to namespace pollution, which you cannot safely ignore. The two options are: a = func() b, c = a[:1], a[1:] del a in which case you may at times fail to del a (probably not a big issue if an … [View More]

It is planned that Just and I use this as a workspace for coordinating and sharing the work to be done, but anyone is invited to jump in with comments or other stuff as well. Thomas

[#527371] sre bug/patch
by Gustavo Niemeyer Nov. 25, 2002

Nov. 25, 2002

Patch #527371, from Greg Chapman, seems to be pretty obvious, and is laying around for quite some time. The same pattern even happens in a few other places in the sre module. I suggest we apply it, including the fixes for lastindex mentioned in the discussion. As a minor observation, I'd include the "state->lastmark = lastmark;" line inside the 'if' block when applying, as every other occurence of this algorithm. No big deal, but saves a few cycles. -- Gustavo Niemeyer [ 2AAC 7928 0FBF … [View More]

Problems installing Python
by John D. Nov. 24, 2002

Nov. 24, 2002

I just installed Python, and got messages something like "network not configured", so it wouldn't built certain modules (https, etc). What causes this? We got this message when we typed: make test I haven't got the time to go through more then 2500 mails from this list in the past 3 weeks to see if anyone else reported this problem. Can someone shed some light on this? John

Expect in python
by Eric S. Raymond Nov. 24, 2002

Nov. 24, 2002

Has anyone else here looked at Pexpect? It's a pure-Python module that uses ptys to support mmost of the capability of Tcl expect. http://pexpect.sourceforge.net/ This is an 0.94 beta, but the author appears to know what he is doing, and it would be an excellent boost to Python's capabilities for administrative scripting. Among other things, it would subsume most of what Tcl is actually used for. I'm thinking this is a very strong candidate to enter the Python library when it reaches 1.… [View More]
