Index.
insert
Make new Index inserting new item at location.
Follows Python list.append semantics for negative values.
Changed in version 3.4.0: Raise IndexError when loc is out of bounds to follow Pandas 1.4+ behavior
Examples
>>> psidx = ps.Index([1, 2, 3, 4, 5]) >>> psidx.insert(3, 100) Int64Index([1, 2, 3, 100, 4, 5], dtype='int64')
For negative values
>>> psidx = ps.Index([1, 2, 3, 4, 5]) >>> psidx.insert(-3, 100) Int64Index([1, 2, 100, 3, 4, 5], dtype='int64')
