How can I remove all selected vertices from all existing vertex groups via script?
Anyone with a hint for me?
Many thanks!

Select the vertex group from which you want to remove the selected vertices, and press the "Remove" button below the list of vertex groups.

$\begingroup$ Oh, okay. I'm not great with scripting, but if you hover the "Remove" button, then it will tell you the command that it runs. You could try just copying that command. It seems like your script will just have to select the vertex first and then remove it by inputting the name of the group you want to remove the vertex from. $\endgroup$ – ElliotThomas Dec 23 '18 at 14:05

Script version of @ElliotThomas answer
These two scripts have to be run in edit mode.
To remove all selected verts from all vertex groups
import bpy
context = bpy.context
ob = context.edit_object
bpy.ops.object.vertex_group_remove_from(use_all_groups=True)
Alternatively can iterate through vertex groups and use the operator on the active group. This example does as above, can be adjusted to skip certain groups.
import bpy
context = bpy.context
ob = context.edit_object
avg = ob.vertex_groups.active
for vg in ob.vertex_groups:
ob.vertex_groups.active = vg
bpy.ops.object.vertex_group_remove_from()
ob.vertex_groups.active = avg
Can also use the api method vg.remove(), for example: to remove verts with indices 0, 1 and 11 from group "Group"
C.object.vertex_groups["Group"].remove([0, 1, 11])
this has to be run in object mode, or will throw an error.
