Re: [Tutor] Finding and Inserting missing dates in a date range.
Ah! but are we sure that the max and min dates are actually in the list? If there are 'missing dates' it might just be possible that it is the max or min date that is missing.

Matt Harrison have some notes and a video of a talk about good python
scripting practices.
He describes some patterns that enable you to write python scripts that
can be chained together as they process data from one and send it to the
next.
See the following links for more info.
http://panela.blog-city.com/oscon_scripting_with_python_handout.htm
http://en.oreilly.com/oscon2009/public/schedule/detail/8317
He created a tool called poachplate so that it is easier to create these
kind of scripts.

Re: [Tutor] using easy_install to download eggs
Snip from PIP http://pypi.python.org/pypi/pip/0.4 Differences From easy_install pip cannot install some packages. Specifically: * It cannot install from eggs. It only installs from source. (Maybe this will be changed sometime, but it's low priority.) If you want to download eggs then you might try basketweaver? http://pypi.python.org/pypi/basketweaver/ basketweaver is a tool for creating your own package index out of a directory full of eggs. You can then point to this index with e.g. zc.buildout or setuptools and thus be independant of PyPI.

Re: [Tutor] using easy_install to download eggs
http://stackoverflow.com/questions/529425/easyinstall-cache-downloaded-files pip (http://pypi.python.org/pypi/pip/) is a drop-in replacement for the easy_install tool and can do that. Just run easy_install pip and set an environment variable PIP_DOWNLOAD_CACHE to the path you want pip to store the files. Note that the cache won't work with dependencies that checkout from a source code repository (like svn/git/hg/bzr). Then use pip install instead of easy_install On Sun, 04 Oct 2009 18:41 +, "Tim Michelsen" wrote: > Hello, > I would like to use easy_install to cache packages registered at PyPi > locally. > > How can I do this for packages? > > I tried the hints from: > http://peak.telecommunity.com/DevCenter/EasyInstall#installing-on-un-networked-machines > > It worked for some packages. > But for others, the command > > easy_install -zxad. mercurial > > just creates a subdirectory and not an *.egg file. > > How can I > 1) use easy_install to download packages from PyPi to a locally saved > egg-file? > 2) use easy_install to download archinves (*.tar.gz / *.zip) to download > the > respective software package from the link indicated on PyPi? > ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

I remember reading some Python tutorials that where written specifically for Astronomers. Did a search on Google.

[Tutor] Examples using Poachplate
Hi Matt Harrison created what appears to be a really nifty tool called poachplate. A python script boilerplate. http://pypi.python.org/pypi?%3Aaction=search&term=poachplate See the following links for more info. http://panela.blog-city.com/oscon_scripting_with_python_handout.htm http://en.oreilly.com/oscon2009/public/schedule/detail/8317 I was wondering if anyone has used this and could direct me to a few simple scripts/examples that used this tool. I guess I'm looking for some tips on how I go start using poachplate to create some simple example scripts.
