pandas.arrays.IntervalArray

class pandas.arrays.IntervalArray(data, closed=None, dtype=None, copy=False, verify_integrity=True)

Pandas array for interval data that are closed on the same side.

New in version 0.24.0.

Parameters

dataarray-like (1-dimensional)

Array-like containing Interval objects from which to build the IntervalArray.

closed{‘left’, ‘right’, ‘both’, ‘neither’}, default ‘right’

Whether the intervals are closed on the left-side, right-side, both or neither.

dtypedtype or None, default None

If None, dtype will be inferred.

copybool, default False

Copy the input data.

verify_integritybool, default True

Verify that the IntervalArray is valid.

Index

The base pandas Index type.

Interval

A bounded slice-like interval; the elements of an IntervalArray.

interval_range

Function to create a fixed frequency IntervalIndex.

cut

Bin values into discrete Intervals.

qcut

Bin values into equal-sized Intervals based on rank or sample quantiles.

Notes

See the user guide for more.

Examples

A new IntervalArray can be constructed directly from an array-like of Interval objects:

>>> pd.arrays.IntervalArray([pd.Interval(0, 1), pd.Interval(1, 5)])
<IntervalArray>
[(0, 1], (1, 5]]
Length: 2, dtype: interval[int64, right]

It may also be constructed using one of the constructor methods: IntervalArray.from_arrays(), IntervalArray.from_breaks(), and IntervalArray.from_tuples().

Attributes

left	Return the left endpoints of each Interval in the IntervalArray as an Index.
right	Return the right endpoints of each Interval in the IntervalArray as an Index.
closed	String describing the inclusive side the intervals.
mid	Return the midpoint of each Interval in the IntervalArray as an Index.
length	Return an Index with entries denoting the length of each Interval.
is_empty	Indicates if an interval is empty, meaning it contains no points.
is_non_overlapping_monotonic	Return a boolean whether the IntervalArray is non-overlapping and monotonic.

Methods

from_arrays(left, right[, closed, copy, dtype])	Construct from two arrays defining the left and right bounds.
from_tuples(data[, closed, copy, dtype])	Construct an IntervalArray from an array-like of tuples.
from_breaks(breaks[, closed, copy, dtype])	Construct an IntervalArray from an array of splits.
contains(other)	Check elementwise if the Intervals contain the value.
overlaps(other)	Check elementwise if an Interval overlaps the values in the IntervalArray.
set_closed(closed)	Return an identical IntervalArray closed on the specified side.
to_tuples([na_tuple])	Return an ndarray of tuples of the form (left, right).
