I would like to get the dictionary a using the dictionary b but it gives me an error.

My code :

a = {"c":"d"}
b = {{"a":"b"}:a}
print(b[{"a":"b"}])

My error :

File main.py in line 2
print(b[{"a":"b"}])
TypeError: unhashable type: 'dict'

    You simply cannot use a dict as a dictionary key - it has to be something hashable, which generally implies being immutable. Ints, strings, tuples are the usual choices. – jasonharper Sep 02 '22 at 19:35
  • I am surprised the second line works. Or are you not showing the actual code causing the error since the error refers to line 2 which is actually line 3?! – luk2302 Sep 02 '22 at 19:37

You cannot use other dictionary as a key, u can only store a dictionary as a value!

example:

a = {
    "key": {"key":"value"}
}
