Is it possible to get the property name from a data_path?

Question

I can copy the data path of any property in the user interface with Copy Data Path which is rigid_body.friction in the example screenshot. Is there a way how to get the property name using the copied data path?

name = getPropertyNameFromDataPath("rigid_body.friction")
print(name) # needs to output "Friction"

Answer 1

import bpy


def get_property_name(data, property) -> str:
    ''' Get the name of a property.

    data (AnyType) - Data from which to take property.
    property (str) - Identifier of property in data.
    return (str) - The name of the property.
    '''
    return data.rna_type.properties[property].name if hasattr(data, property) else ''


name = get_property_name(bpy.context.object.rigid_body, 'friction')

print(name)

Answer 2

A big thank you to @Karan for directing me into the right path. I was able to come up with a general solution for any data path (Right click RMB any property in the user interface > Copy Data Path) and then use the function:

def get_property_name(data_path) -> str:
    s = data_path
    i = s.find('.')
    data_path_1 = ""
    data_path_2 = s
    if i > 0:
        ri = s.rindex('.')
        data_path_1 = '.' + s[0:ri]
        data_path_2 = s[ri+1:len(s)]
    data = eval("bpy.context.object" + data_path_1)
    return data.rna_type.properties[data_path_2].name if hasattr(data, data_path_2) else ''

Sample Outputs:

print(get_property_name('rotation_euler'))
print(get_property_name('rigid_body.collision_shape'))
print(get_property_name('modifiers["Bevel"].width'))
print(get_property_name('modifiers["Fluid"].flow_settings.surface_distance'))

# outputs:
#
# Eurler Rotation
# Collision Shape
# Width
# Surface Emission

Use Full Data Path instead of Data Path

import bpy


def get_property_name_from_data_path(data_path) -> str:
    ''' Get the name of a property.

    data_path (str) - Data path from which to take data and property.
    return (str) - The name of the property.
    '''
    data = eval('.'.join(data_path.split('.')[:-1]))
    property = data_path.split('.')[-1]
    if property == 'default_value':
        return data.name

    return data.rna_type.properties[property].name if hasattr(data, property) else ''

name = get_property_name_from_data_path('bpy.data.materials["Material"].node_tree.nodes["Principled BSDF"].inputs[2].default_value')

print(name)
