TypeError: unhashable type: usually happens when you try to use something unhashable as a key in a hash indexed data structure (e.g. dict, set). Looking at where you might be using list as a hash table index, the only part that might do it is using [HOST]ating frequencies is often done with a hash table TypeError: unhashable type: 'dict' What's the canonical way to check for type in Python? Change column type in pandas. 3 Can I tell PyInstaller to package my entire source tree? How do I type hint a 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 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 reason you're getting the unhashable type: 'list' exception is because k = list[0:j] sets k to be a "slice" of the list, which is logically another, often shorter, list. What you need is to Python dictionary: TypeError: unhashable type: 'list' Ask Question. Asked 12 years, 2 months ago. Modified 1 year, 11 months ago. Viewed k times. I'm 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
TypeError: unhashable type: 'list' from attempt to create dict
If you try to use the unhashable key type ‘dict’ when adding a key or retrieving a value, you will raise the error “TypeError: unhashable type: ‘dict'”. This tutorial will go through the In your snippet, it looks like val is a dict and you are asking Python if this val is one of the values present in the set. In response, Python attempts to hash val, but this fails. The hurdle you have to overcome is that some of the values in your outer dict are themselves a dict, whereas other values look like list, str or int Unhashable type: dict with test JSON. When I try to test some JSON in the python interpreter I get the error. I'm not sure why. File "", line 6, in. The Python "TypeError: unhashable type: 'dict'" occurs when we use a dictionary as a key in another dictionary or as an element in a set. To solve the error, TypeError: unhashable type: ‘dict’ Dictionary in Python is an unordered collection to store data values in key:value pairs. Key acts as an identifier to access and retrieve the value in the dictionary. The keys can contain only immutable hashable types such as strings, boolean, integers, tuples are hashable, which means the value doesn’t The value of body is a set ({ } without key-value is a set literal, e.g., {1,2} is a set). Inside this set you have a dictionary. Items in a set have to be hashable, and dictionary isn't. As the comment from @Carcigenicate says, it seems like a typo of having { { }} instead of { } for the value of body. Elasticsearch documentation shows that 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) 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
Python JSON unhashable type: 'dict' - Stack Overflow
You're already printing links[i], so it should have come to your attention that each element of the links list is also a list.. A dictionary can't contain a list as a key, since dictionaries are based on a hash table and lists can't be hashed. Tuples can be hashed though, and they're very similar to lists, so you could try converting the list to a tuple 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 Error: unhashable type: 'dict' with @dataclass. name: str. signature: Dict[str, Type[DBType]] prinmary_key: str. foreign_keys: Dict[str, Type[ForeignKey]] indexed: List[str] Don't understand what's the problem. frozen=True prevents you from assigning new values to the attributes; it does not prevent you from mutating the existing mutable values 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) The variables get printed perfectly on my shell, however django doesn't want to pass them to the templates, I keep getting TypeError: unhashable type: 'dict' but I'm 3 Answers. The code if foo in {} checks if any of the keys of the dictionary is equal to foo. In your example, foo is a list. A list is an unhashable type, and cannot be the key of a dictionary. If you want to check if any entry of a list is contained in a dictionaries' keys or in a set, you can try: if any ([x in {} for x in (4, 5, False)])
