pymel.core.general.listNodeTypes

listNodeTypes(*args, **kwargs)

Lists dependency node types satisfying a specified classification string. See the ‘getClassification’ command for a list of the standard classification strings.

Flags:

Long name (short name)		Argument Types	Properties
exclude (ex)		unicode
	Nodes that satisfies this exclude classification will be filtered out.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.listNodeTypes

Example:

import pymel.core as pm

pm.listNodeTypes( 'shader' )
