Message emitted:

Consider using dict.get for getting values from a dict if a key is present or a default if not

Description:

Using the builtin dict.get for getting a value from a dictionary if a key is present or a default if not, is simpler and considered more idiomatic, although sometimes a bit slower

Problematic code:

knights = {"Gallahad": "the pure", "Robin": "the brave"}

if "Gallahad" in knights:  # [consider-using-get]
    DESCRIPTION = knights["Gallahad"]
else:
    DESCRIPTION = ""

Correct code:

knights = {"Gallahad": "the pure", "Robin": "the brave"}

description = knights.get("Gallahad", "")
