Re: speed up pandas calculation

= df[keep_col] is not fast but it is not that slow. You made me think of a solution to that part. just slice and copy. The only gotya is that the keep_col have to actually exist keep_col = ['PATCODE', 'PATWT', 'VDAYR', 'VMONTH', 'MED1', 'MED2', 'MED3', 'MED4', 'MED5'] df = df[keep_col] The real slow part seems to be for n in drugs: df[n] = df[['MED1','MED2','MED3','MED4','MED5']].isin([drugs[n]]).any(1) Vincent Davis 720-301-3003 -- https://mail.python.org/mailman/listinfo/python-list

print formating for matrix/table

ne. I would have thought I could find a prebuilt function to do this. Surly lots of people are printing matrixes and would like nice formating. So what am I missing? Vincent Davis 720-301-3003 -- http://mail.python.org/mailman/listinfo/python-list

question about Z=[[x for y in range(1,2) if AList[x]==y] for x in range(0,5)]

Z=[[x for y in range(1,2) if AList[x]==y] for x in range(0,5)] I am not sure how to ask this but which "for" is looped first? I could test but was wondering if there was a nice explanation I could apply to future situations. Thanks Vincent Davis 720-301-3003 -- http://mail.python.o

Re: Use list name as string

I know nothing but that sucks. I can think of a lot of times I would like to do something similar. There really is no way to do this, it seems like there would be some simple way kind of like str(listname) but backwards or different. Thanks Vincent Davis On Wed, Feb 4, 2009 at 10:07 AM, MRAB

Re: Use list name as string

I guess what I am saying is that it does not seem like I am adding any information that is not already there when I have to enter that list and list name after all they are the same. Thanks Vincent Davis On Wed, Feb 4, 2009 at 10:18 AM, Vincent Davis wrote: > I know nothing but that sucks
