Storing and Retrieving Values
The three methods you will reach for most often are ctx.set_state(), ctx.get_state(), and ctx.delete_state(). All three are asynchronous, so you always call them with await.
To store a value, you give it a string key and a value:
await ctx.set_state("last_breed", "labrador")
To retrieve it in a later call, use the same key:
breed = await ctx.get_state("last_breed")
