map in Python
I have recently switched over to Python from Perl. I want to do
something like this in Python:
@test = ("a1", "a2", "a3");
map {s/[a-z]//g} @test;
print @test;
However, I take it there is no equivalent to $_ in Python. But in that
case how does map pass the elements of a sequence to a function? I
tried the following, but it doesn't work because the interpreter
complains about a missing third argument to re.sub.
import re
test = ["a1", "a2", "a3"]
map(re.sub("[a-z]", ""), test)
print test
Thanks in advance.
Regards,
Stuart

jedit http://www.jedit.org/ much better than textpad by a longshot. but whatever you choose... -stu -- http://mail.python.org/mailman/listinfo/python-list

Great example of a python module/package following up to date conventions.
I'm hoping someone on here can point me to an example of a python package that is a great example of how to put it all together. I'm hoping for example code that demonstrates: -Strict adherence to PEP 8 -thorough use of Docstrings -Conventional directory structure/package layout -Appropriate use of the latest accepted coding guidelines in the python community (e.g., new classes versus old classes, Python 3000 compatibility, newer language features, etc. etc.) -Some amount of object oriented design Bonus: -Unit tests -Logging mechanism I can't imagine a package that's been around longer than a few years will hit upon all these things well unless the maintainer went back and did some serious refactoring and re-tooling. Is this question possible to answer? -- http://mail.python.org/mailman/listinfo/python-list

I was hoping to have a template of a 3rd party package to follow. Complete with conventions to follow for easily packaging and distributing via the usual python channels (pypi, easy_install, egg, etc.). -- http://mail.python.org/mailman/listinfo/python-list

And grepping in the /usr/lib/python2.5/ folder for import statements on various things I'm interested in is bringing up some good examples to check out as well. Given that I'm still fairly novice to this I'm not yet in the position to make a good judgment on what is and isn't a good python practice so I was hoping someone on here might be able to point at a module or 2 that has really done a good job of following best practices. Seems like a reasonable question with an answer that others in a similar position to me might find useful. -- http://mail.python.org/mailman/listinfo/python-list
