2. most probably [HOST]les [0] or [HOST]les [1] is a list and you can not use this line: if row not in assignment or column not in assignment: ex of search of a list in a dict: [] in {1: 2} output: TypeError: unhashable type: 'list'. also, you may check your variable col which it is not defined in your function, this may be a list If not (code in dictionary): TypeError: unhashable type: 'dict'. for code in compressed: if not (code in dictionary): dictionary[code] = string + (string[0]) I've looked at the following links to figure out where I should freeze my code. TypeError: unhashable type: 'dict'. TypeError: unhashable type: 'dict', when dict used as a key for another dict. TypeError: unhashable type: 'dict' in python. def getPx (self, date, instrument, item = 'Adj Close', prices = None): ''' get a price for an instrument Hello. I have only been using Dash a few weeks and I’m now trying pattern matching callbacks. My app works completely fine as a standalone app (not sure if this is the correct terminology), but returns TypeError: unhashable type: ‘dict’ when integrating it into my Django project as a stateless Django app. There appears to be 2 problems: 1. TBH, I find it confusing that dictionaries and sets use basically identical syntax. With two elements, the only thing that makes it possible to distinguish between a dictionary and a set is the symbol in the middle:: or, Even worse, {} constructs an empty dictionary, while it seems more logical for it to construct a set. – ForceBru Below are some of the solution for TypeError: Unhashable Type ‘Dict’ Exception in Python: Use Immutable Types for Keys. In this example, the code creates a

Traceback (most recent call last): File "J:#", line 21, in data = {name: {user_details}} TypeError: unhashable type: 'dict' So as far as I understood, we cannot use dictionary as a key in a dict "key: value" relationship. This is the part of the code causing the issue on line 21 The Python TypeError: unhashable type: 'dict' can be fixed by casting a dictionary to a hashable object such as tuple before using it as a key in another dictionary: print (my_dict) In the example above, the tuple () function is used to convert the dictionary to a tuple. The above code runs successfully and produces the correct output
How to fix TypeError: unhashable type: 'dict' - sebhastian
The Hashable type can be used as a key in a dictionary. A dict() will always call __hash__ for the underlying key. Now for your case, it seems weird that you are iterating over a list from [HOST]()["data" ] storing that in i and then using that to index into [HOST]() it seems unrelated From python documentation: An object is hashable if it has a hash value which never changes during its lifetime (it needs a hash () method), and can be compared to other objects (it needs an eq () method). Hashable objects which compare equal must have the same hash value. Hashability makes an object usable as a dictionary key and
