bokeh.core.enums

Common enumerations to be used together with Enum property.

This module provides many pre-defined enumerations, as well as functions for creating new enumerations.

New enumerations can be created using the enumeration() function:

#: Specify a nautically named side, port or starboard
MyEnum = enumeration("port", "starboard")

Typically, enumerations are used to define Enum properties:

from bokeh.model import Model
from bokeh.core.properties import Enum

class MyModel(Model):

    location = Enum(MyEnum, help="""
    Whether the thing should be a port or starboard.
    """)

Enumerations have a defined order and support iteration:

>>> for loc in MyEnum:
...     print(loc)
...
port
starboard

as well as containment tests:

>>> "port" in MyEnum
True

Enumerations can be easily documented in Sphinx documentation with the bokeh_enum Sphinx extension.


enumeration(*values, **kwargs)[source]

Create an enumeration() object from a sequence of values.

Call enumeration with a sequence of (unique) strings to create an Enumeration object:

#: Specify the horizontal alignment for rendering text
TextAlign = enumeration("left", "right", "center")
Parameters:values (str) –

string enumeration values, passed as positional arguments

The order of arguments is the order of the enumeration, and the first element will be considered the default value when used to create Enum properties.

Keyword Arguments:
 case_sensitive (bool, optional) – Whether validation should consider case or not (default: True)
Raises:ValueError if values empty, if any value is not a string or not unique
Returns:Enumeration
