redis.exceptions.ResponseError: Invalid graph operation on empty key

[szabgab]

When running the Python example from the main page https://docs.falkordb.com/
I get an exception:

redis.exceptions.ResponseError: Invalid graph operation on empty key

This happens as it tries to delete a not-existing graph.

If there is an exists method that would be probably the best to call that, but at least it could be wrapped in a try - except block

try:
    g.delete()
except Exception:
    # Graph doesn't exist yet, which is fine
    pass
