Yeah long time no post indeed! 
Anyways, yes looks like it gonna work but what if you try to search single or double quotes? (Not a python dev so not sure how you will search for a single quote in below code)
for o in collection.query.fetch_objects(
filters=wvc.query.Filter.by_property("skills").contains_any([" \' "])
).objects:
print(o.properties)
