Use &
to perform a logical AND operation in Pandas DataFrame.
Consider the following DataFrame:
A B0 True True1 False True2 False False
To perform a bit-wise logical AND operation between columns A and B:
df["A"] & df["B"]
0 True1 False2 Falsedtype: bool
Here, a True
is returned for the first row because both columns A
and B
have True
as the first row.
