How to remove outliers from a dataset
I've got some multivariate data of beauty vs ages. The ages range from 20-40 at intervals of 2 (20, 22, 24....40), and for each record of data, they are given an age and a beauty rating from 1-5. When I do boxplots of this data (ages across the X-axis, beauty ratings across the Y-axis), there are so...
Normalize data in pandas
...ay you have values [-5,1,10] in a sample, but want to normalize based on a range of -7 to 7 (so anything above 7, our "10" is treated as a 7 effectively) with a midpoint of 2, but shrink it to fit a 256 RGB colormap:
#In[1]
NormData([-5,2,10],low=-7,center=1,hi=7,shrinkfactor=2./256)

Split Strings into words with multiple word boundary delimiters
...pression is here to prevent the special interpretation of - as a character range indicator (as in A-Z),
the + skips one or more delimiters (it could be omitted thanks to the filter(), but this would unnecessarily produce empty strings between matched separators), and
filter(None, …) removes the em...

Making a WinForms TextBox behave like your browser's address bar
...t fails in one specific case. If you give the TextBox focus by selecting a range of text instead of just clicking, the alreadyFocussed flag doesn't get set to true, so when you click in the TextBox a second time, all the text gets selected.
Here is my version of the solution. I've also put the code...
