Basic set and get operations

Start off by connecting to the valkey server

To understand what decode_responses=True does, refer back to this document

import valkey

r = valkey.Valkey(decode_responses=True)
r.ping()

True

The most basic usage of set and get

r.set("full_name", "john doe")

True

r.exists("full_name")

1

r.get("full_name")

'john doe'

We can override the existing value by calling set method for the same key

r.set("full_name", "overridee!")

True

r.get("full_name")

'overridee!'

It is also possible to pass an expiration value to the key by using setex method

r.setex("important_key", 100, "important_value")

True

r.ttl("important_key")

100

A dictionary can be inserted like this

dict_data = {
    "employee_name": "Adam Adams",
    "employee_age": 30,
    "position": "Software Engineer",
}

r.mset(dict_data)

True

To get multiple keys’ values, we can use mget. If a non-existing key is also passed, Valkey return None for that key

r.mget("employee_name", "employee_age", "position", "non_existing")

['Adam Adams', '30', 'Software Engineer', None]
