Pandas boolean statements : I am working with some messy EPA data that desperately needs to be cleaned up. It looks something like this:
----------
id   1    2     3     4
1    ph   temp  alk   cond
2    ph   temp  alk   cond
3    temp ph    cond  alk
4    temp alk   cond  ph
----------

We would like to make new columns 'ph', 'temp', 'alk', 'cond', etc. while maintaining everything else in the row.
