How does python dictionary matching work?

1 points · submitted Jun 2021 by u/codeforces_help

Does it go as many levels as the nesting is in the dictionary?

I am to confirm that matching happens on all the levels with value equality.

I am looking for the actual equality implementation source as well.

What do you mean by "matching", exactly?

codeforces_help [OP] 1 points · Jun 2021

By matching I mean given two json values, with lets say 5 level of nesting for some key, how does matching work. Does it really go accessing each and every level to match the values at that level?

Can you post a code example?

codeforces_help [OP] 1 points · Jun 2021

Consider the following json : 

{
    "a": {
        "b": [1, 2, 3, {
            "c": {
                "d": (99, "if", "hello", {
                    "f": "98"
                })
            }
        }]
    }
}

Given another similar json or even this same json on the right side of equality operator, how would that work? Does it really go level by level, every path matching keys and values?

Yes, it does.

What is 'dictionary matching' supposed to mean? Do you mean comparing dictionaries? Finding a value in a dictionary? Something else?

As for the source Python is open source on Github
