Pandas boolean DataFrame selection ambiguity

Question

EDIT: Fixed values in tables.

Let\'s say I have a pandas dataframe df:

>>>df
                  a         b         c
        0  0.016367  0.         


        

Answer 1

Since the logical operators are not overridable in python, numpy and pandas override the bitwise operators.

This means you need to use the bitwise-or operator:

df[(df > 0.5) | (df < 0)]
