Return self._q_values[state][action] Either state ir action contains the bad value. You could add a print into the function to see what is being used 8. The docs say: A Counter is a dict subclass for counting hashable objects. In your case it looks like results is a dict containing list objects, which are not hashable. If you are sure that this code worked in Python 2, print results to see its content. Python + (default, Oct 9 , ) >>> from collections import Counter 1 Answer. When you attempt to use (args,kwargs) as key (or part of the key) in cache [ (args,kwargs)], kwargs is of dict type. dict types are not able to be used as keys in dictionaries. In fact, no mutable data structures can be used as keys in dictionaries. An alternative is to use tuple ([HOST] ()) as this part of the key in the cache The Problem. We know that the python dictionary expects a key-value pair and the key must be a washable object. In my program, I have declared a dictionary and named its fruits. It has two keys, one is name and another one is stock and I want to see which fruits are in plenty amount in stock Since the item code has a 1-to-1 correspondence with the values in the a and b columns, it suffices to merge on item alone. Since the values in the item column are hashable, there is no problem merging: suffixes=['', '_y']) result[col].update(result[col+'_y']) result[col] = result[col].fillna(0) 2. i have 2 data frames ds and dk and want to merge that with a common column result using the merge command: result = [HOST](ds,dk,on='result') but the result column is actually a dictionary and resulting in the error: "unhashable type: dict". what is the possible solution for merging these frames?

Python - unhashable type error in urllib2 - Stack Overflow
You can serialize dictionary parameter to string and unserialize in the function to the dictionary back. Works like a charm. the function: @lru_cache() def data_check(serialized_dictionary): my_dictionary = [HOST](serialized_dictionary) print(my_dictionary) the call I am simply trying to create the dictionary, not calling any keys from it. As I understand from TypeError: unhashable type: 'dict', I can use frozenset() to get keys. When an unhashable object is added to a set or used as a key in a dictionary, a TypeError is raised because the object's hash value can change (when we 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 1 Answer. Sorted by: 0. You can't use a dict as a key (it's mutable - see the description of frozenset for an explanation). It looks like you're supposed to pass some torrent_id to remove, and whatever this is, it must be something hashable - ie, not a dict. Share. Improve this answer. Follow What Does TypeError Mean?

Python 3.x - TypeError: unhashable type: 'dict'. Unable to read …
Cameron (Cameron Simpson) October 30, , am 2. This means that you’re using an unhashable value as a key in a dict or. set. Keys need to be hashable for these to work because fast lookup is. based on dividing values into small “buckets”, each of which contains. very few values (ideally just 0 or 1 value) Zip returns a list of tuples, not a tuple.. Besides, a tuple is only hashable if each of its elements are hashable. So a tuple of lists will not be hashable either. That said, there's nothing wrong with dict(zip(keys, values)) if keys is a list of hashable elements. Your problem is that datelist contains lists (results of [HOST]l) which are not hashable and The “TypeError: unhashable type: ‘dict'” error typically occurs when you use a dictionary as a key in a Python set. This error message indicates that you’ve tried to use an I understand that dicts/sets should be created/updated with hashable objects only due to their implementation, so when this kind of code fails >>> {{}} # empty dict of empty dict Traceback (most recent call last): File "", line 1, in TypeError: unhashable type: 'dict' it's ok and I've seen tons of this kind of messages 2, 7 32 If the below answer solved your issue mark it as correct, please.
