Python Pandas: Boolean indexing on multiple columns

Question

(This question already has answers here): question from:https://stackoverflow.com/questions/17216153/python-pandas-boolean-indexing-on-multiple-columns

Answer 1

It is a precedence operator issue.

You should add extra parenthesis to make your multi condition test working:

d[(d['x']>2) & (d['y']>7)]

This section of the tutorial you mentioned shows an example with several boolean conditions and the parenthesis are used.
