Detail: Index: Dictionary-Like

Index.__contains__(value)[source]

Return True if value in the labels.

>>> ix = sf.Index(('a', 'b', 'c', 'd', 'e'), name='x')
>>> ix
<Index: x>
a
b
c
d
e
<<U1>
>>> ix.__contains__('a')
True

Index.__iter__()[source]

Iterate over labels.

>>> ix = sf.Index(('a', 'b', 'c', 'd', 'e'), name='x')
>>> ix
<Index: x>
a
b
c
d
e
<<U1>
>>> tuple(ix.__iter__())
('a', 'b', 'c', 'd', 'e')

Index.__reversed__()[source]

Returns a reverse iterator on the index labels.

>>> ix = sf.Index(('a', 'b', 'c', 'd', 'e'), name='x')
>>> ix
<Index: x>
a
b
c
d
e
<<U1>
>>> tuple(ix.__reversed__())
('e', 'd', 'c', 'b', 'a')

Index.values

A 1D NumPy array of the values in the Index. This array will have the same dtype as the container.

>>> ix = sf.Index(('a', 'b', 'c', 'd', 'e'), name='x')
>>> ix
<Index: x>
a
b
c
d
e
<<U1>
>>> ix.values_at_depth(0)
['a' 'b' 'c' 'd' 'e']
