pymel.core.general.removeMultiInstance

removeMultiInstance(*args, **kwargs)

Removes a particular instance of a multiElement. This is only useful for input attributes since outputs will get regenerated the next time the node gets executed. This command will remove the instance and optionally break all incoming and outgoing connections to that instance. If the connections are not broken (with the -b true) flag, then the command will fail if connections exist.

Flags:

Long name (short name)		Argument Types	Properties
b (b)		bool
	If the argument is true, all connections to the attribute will be broken before the element is removed. If false, then the command will fail if the element is connected.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.

Derived from mel command maya.cmds.removeMultiInstance

Example:

import pymel.core as pm

pm.createNode('choice',n='choice')
# Result: nt.Choice(u'choice') #
pm.setAttr('choice.input[0]',2.0)
pm.setAttr('choice.input[4]',4.0)
pm.connectAttr('choice.input[8]','choice.input[100]')

# This will remove the element with index 4 from the input of
# the choice node as long as there are no incoming or outgoing
# connections to the attribute.
#
pm.removeMultiInstance( 'choice.input[4]' )

# This will remove the element with index 100 from the input of
# the choice node, breaking any existing connections first.
#
pm.removeMultiInstance( 'choice.input[100]', b=True )
