To explain what I mean, I’m adding keys and values to a dictionary but if a key in the dictionary has a value that’s the name of another key, I want that key to be assigned the other key’s value. For example, if I have dict1 = {"a": 100, "b": 200, "c": "a"}
is it possible to change the value of c to 100 (which is a’s value)? So instead it would be
dict1 = {"a": 100, "b": 200, "c": 100}
The code I have right now is obviously wrong and giving me an error but I was trying to type out what I thought would work
for x, y in dict1.items(): if dict1[x] == dict1[x]: dict1[x] = dict1[y] print(x, y)

Answer
You can use:
my_dict = {"a": 100, "b": 200, "c": "a"} for k, v in my_dict.items(): if v in my_dict: my_dict[k] = my_dict[v]
You can alternatively use a dict comprehension:
result = { k: my_dict[v] if v in my_dict else v for k, v in my_dict.items() }
Output:
{'a': 100, 'b': 200, 'c': 100}
