Access key values of dictionary with tuple as key

Question

I have dictionary dict like this, with tuples as keys:

 dict = { (1, 1): 10, (2,1): 12}

and tried to access it like this :

new_dict = {}
for key, value in dict: 
    new_dict["A"] = key[0]
    new_dict["B"] = key[1]
    new_dict["C"] = value

But it fails, since key does not seem to resolves to a tuple. What is the correct way?

You can try `for key, value in dict.items():` if you are using Python 3 — Harun Yilmaz, Jan 27 '20 at 13:49

To iterate over key value pairs, use the .items() method of the dict.

Also, give the dictionary a name like my_dict to avoid overwriting the builtin dict.

new_dict = {}
for key, value in my_dict.items(): 
    new_dict["A"] = key[0]
    new_dict["B"] = key[1]
    new_dict["C"] = value
