How to get a list of all indexes in python-elasticsearch

This question comes up when searching for information on retrieving aliases using the python-elasticsearch library. The accepted answer says to use get_aliases but that method has been removed (as of 2017). To get aliases, you can use the following:

 es.indices.get_alias("*")

UPDATE

The latest usage should be with a keyword arg:

es.indices.get_alias(index="*")
