pandas should always be imported as ‘import pandas as pd’

PD005

Use arithmetic operator instead of method

PD006

Use comparison operator instead of method

PD007

‘.ix’ is deprecated; use more explicit ‘.loc’ or ‘.iloc’

Use ‘.loc’ instead of ‘.at’. If speed is important, use numpy.

PD009

Use ‘.iloc’ instead of ‘.iat’. If speed is important, use numpy.

PD010

‘.pivot_table’ is preferred to ‘.pivot’ or ‘.unstack’; provides same functionality
