comment Apply Number formatting to Pandas HTML CSS Styling
stick to using just the formatters for now - I don't see a way to work around this issue for now - I guess the .bar and highlight_min, highlight_max etc. should all take kwargs for the column data formats, could you file an issue for that on github.com/pydata/pandas so that the maintainers can track it, maybe link the PR from my answer to the issue as well.

The order was different because I was being stupid, but I'll keep that in mind.

comment pandas multiindex assignment from another dataframe
I see that's a good explanation, thanks. I like the df_.values, especially because it allows you to do all kinds of crazy partial assignments. Just need to be careful to index the data frames in the same order, I was wondering why some of my data suddenly flips around (oops).

comment pandas multiindex assignment from another dataframe
doesn't the dummy index at the end create a view of the data frame as documented here - I at least get the warning about assigning values to a view

comment Topic Modelling in MALLET vs NLTK
If you're using gensim you might as well go with the online lda version in gensim.models.ldamodel.LdaModel instead of the mallet one, unless you really really want to use the Gibbs sampling variety that mallet implements.
