+---------------

+As you may already know, properties may also have list instead of scalar

+
+   import caosdb as db
+   db.Property(name="TestList", datatype=db.LIST(db.DOUBLE)).insert()
+   db.RecordType(name="TestType").add_property(name="TestList").insert()
+   db.Record(name="TestRec").add_parent("TestType").add_property(
+       name="TestList", value=[1,2,3]).insert()
+   retrieved = db.Record(name="TestRec").retrieve()
+   retrieved.get_property("TestList").value += [4,5]
+   retrieved.update()
+
+   # Check update
+   retrieved = db.Record(name="TestRec").retrieve()
+   print(retrieved.get_property("TestList").value)
