Check this function, it already has type hints:

{* ../../docs_src/python_types/tutorial003.py hl[1] *}

Because the editor knows the types of the variables, you don't only get completion, you also get error checks:

Now you know that you have to fix it, convert `age` to a string with `str(age)`:

            this.reconnecting = false;
        }
        
        public boolean isExpired() {
            if (type == HandleType.PERSISTENT) {
                return false;  // Persistent handles don't expire
            }
            long elapsed = System.currentTimeMillis() - lastAccessTime;
            return elapsed > timeout;
        }
        
        public void updateAccessTime() {

				time.Unix(0, 3).UTC(),
				time.Unix(0, 3).UTC(),
			},
			time.Unix(0, 3).UTC(),
			4,
		},
		{
			// 3. Tests common time obtained when elements have a mixture of
			// sentinel values and don't have read quorum on any of the values.
			[]time.Time{
				time.Unix(0, 3).UTC(),
				time.Unix(0, 3).UTC(),
				time.Unix(0, 2).UTC(),
				time.Unix(0, 1).UTC(),
				time.Unix(0, 3).UTC(),
