It's a bioconductor extension to rpy2 http://www.bitbucket.org/lgautier/rpy2-bioc-extensions/overview/ I am trying to learn R and at they same time more about python and R bioconductor packages. So no it is not homework but I am trying to learn something. I am sure the answer is obvious when you know it :) Here is the class, although it is obviously part of something bigger, you can checkout the full code at bitbuckit.org class BString(XString): """ Biological string """ _bstring_constructor = biostrings.BString @classmethod def new(cls, x): """ :param x: a (biological) string """ res = cls(cls._bstring_constructor(conversion.py2ri(x))) _setExtractDelegators(res) return res *Vincent Davis 720-301-3003 * vinc...@vincentdavis.net my blog <http://vincentdavis.net> | LinkedIn<http://www.linkedin.com/in/vincentdavis> On Mon, Apr 5, 2010 at 1:08 PM, Alan Gauld <alan.ga...@btinternet.com>wrote: > "Vincent Davis" <vinc...@vincentdavis.net> wrote > >> I am working an a open source project and would like to add feature to a >> >> class. >> Current action: >> in: >>>b = BString.new('I am a BString object') >> > > That' a very strange idiom in Python. > Can you show us the class definition? > > > out: >>>b >> in: >>><BString - Python:0x1044846c8 / R:0x105c86f50> >> in: >>>print(b) >> out: >>> 21-letter "BString" instance >> seq: I am a BString object >> >> What I would like is to be able to >> in >>>b >> out >>>21-letter "BString" instance >> seq: I am a BString object >> >> I have 2 questions >> 1, how do I do this? >> 2, how does print know what to do? >> > > If you look at your class definition that should become obvious. > Are you sure this isn't a homework? > > > -- > Alan Gauld > Author of the Learn to Program web site > http://www.alan-g.me.uk/ > > _______________________________________________ > Tutor maillist - Tutor@python.org > To unsubscribe or change subscription options: > http://mail.python.org/mailman/listinfo/tutor >
