pandas.Series.between

Series.between(left, right, inclusive=True)

Return boolean Series equivalent to left <= series <= right.

This function returns a boolean vector containing True wherever the corresponding Series element is between the boundary values left and right. NA values are treated as False.

Parameters:

left : scalar

Left boundary.

right : scalar

Right boundary.

inclusive : bool, default True

Include boundaries.

Returns:

Series

Each element will be a boolean.

pandas.Series.lt

Less than of series and other

Notes

This function is equivalent to (left <= ser) & (ser <= right)

Examples

>>> s = pd.Series([2, 0, 4, 8, np.nan])

Boundary values are included by default:

>>> s.between(1, 4)
0     True
1    False
2     True
3    False
4    False
dtype: bool

With inclusive set to False boundary values are excluded:

>>> s.between(1, 4, inclusive=False)
0     True
1    False
2    False
3    False
4    False
dtype: bool

left and right can be any scalar value:

>>> s = pd.Series(['Alice', 'Bob', 'Carol', 'Eve'])
>>> s.between('Anna', 'Daniel')
0    False
1     True
2     True
3    False
dtype: bool
