Selecting multiple columns in a pandas dataframe
...mns, like df.ix[0, 'Col1':'Col5']. That gets all columns that happen to be ordered between Col1 and Col5 in the df.columns array. It is incorrect to say that ix indexes rows.

Think of running a naive but simpler implementation (so less likely to contain errors) of the same algorithm to check correctness. Or a check by exhaustive enumeration of so...
