Deleting rows based on multiple conditions Python Pandas

Question

I want to delete rows when a few conditions are met:

For instance, a random DataFrame is generated:

import pandas as pd
import numpy as np
df = pd.Da         


        

Answer 1

For reasons that aren't 100% clear to me, pandas plays nice with the bitwise logical operators | and &, but not the boolean ones or and and.

Try this instead:

df = df[(df.one > 0) | (df.two > 0) | (df.three > 0) & (df.four < 1)]
