Use & to perform a logical AND operation in Pandas DataFrame.

Consider the following DataFrame:

import pandas as pd
df = pd.DataFrame({"A":[True,False,False],"B":[True,True,False]})
df
A B
0 True True
1 False True
2 False False

To perform a bit-wise logical AND operation between columns A and B:

df["A"] & df["B"]
0 True
1 False
2 False
dtype: bool

Here, a True is returned for the first row because both columns A and B have True as the first row.
