Why dict get key instead of dict key

Question

Today, I came across the dict method get which, given a key in the dictionary, returns the associated value.

For what purpose is this function useful? If I wanted to find a value associated with a key in a dictionary, I can just do dict[key], and it returns the same thing:

dict = {"Name": "Harry", "Age": 17}
dict["Name"]
dict.get("Name")
