In Maya how to quickly delete the same components on multiple objects through Python. (Got asked this by a friend)

delete_list_of_components_on_selection.py

# Delete all components in the `components` list from the selected nodes
from maya import cmds


components = [
    ".f[4096]",
    ".f[3005:3055"],
    # etc.
]

to_delete = []
for node in cmds.ls(selection=True, long=True, objectsOnly=True):
    for component in components:
        to_delete.append(f"{node}{component}")

if to_delete:
    cmds.delete(to_delete)

delete_single_face.py

from maya import cmds

index = 9604

for node in cmds.ls(selection=True, long=True, objectsOnly=True):
    cmds.delete(f"{node}.f[{index}]")

print_selected_components.py

# Print all the selected components as a list of just the components
from maya import cmds

selection = cmds.ls(sl=1)
components = set()
for selected in selection:
    if "." in selected:
        component = "." + selected.split(".", 1)[-1]
        components.add(component)
components = list(sorted(components))

print(components)

reselect_all_objects_with_same_component_selection.py

# Reselect all selected objects with the same components
from maya import cmds

selection = cmds.ls(selection=True)
components = set()
for selected in selection:
    if "." in selected:
        component = "." + selected.split(".", 1)[-1]
        components.add(component)
components = list(sorted(components))

if components:
    to_select = []
    for node in cmds.ls(selection=True, objectsOnly=True, long=True):
        for component in components:
            to_select.append(f"{node}{component}")
    cmds.select(to_select, replace=True, noExpand=True)
else:
    print("No components found in selection.")
