File "", line 1, in. TypeError: unhashable type: 'slice'. What you are trying to do is take n items from the collection. So the way to achieve this is to first convert the dict to a list (which is sliceable). To do this use [HOST], [HOST] or [HOST] depending on your use case 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) Lists have an immutable equivalent, called a 'tuple'. This is how you would write a piece of code that took a list of lists, removed duplicate lists, then sorted it in reverse. result = sorted (set (map (tuple, my_list)), reverse=True) Additional note: If a tuple contains a list, the tuple is still considered mutable TypeError: unhashable type: 'dict' 1 TypeError: unhashable type: 'dict' in python. 17 Pymongo API TypeError: Unhashable dict. 8 unhashable type: dict with test JSON. 0 Python unhashable dict. 1 unhashable type: 'dict_keys' TypeError: unhashable type: ‘dict’. Dictionaries consist of two parts: keys and values. Keys are the identifiers that are bound to a value. When you reference a key, you’ll be able to retrieve the value associated with that key. Only hashable objects can be keys in a dictionary 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 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

Asking for help, clarification, or responding to other answers 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). The distribution of values is based on the hash function of the key. In order for dictionary The major problem with this method is that the entered password is printed out when you type it in. To get around this, use the [HOST]s() function. Share Learn about alternatives to dictionaries for unhashable types and to avoid “TypeError: Unhashable Type: dict”. Understanding TypeErrors in Python. In the world of Python programming, TypeErrors are a common stumbling block that developers encounter.

Type checking and input validation: One of the best ways to prevent TypeErrors is to perform type checking and input validation. Before performing any TypeError: unhashable type: 'Series' - can't work out how to pass a one column df as a non-series object if even possible? I do not see the uniqueId initialization but it seems that it is a dictionary type. You can check keys in the dictionary but the keys are hashed. To search by key, Short story in which time slips and the passenger 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? This will never work, so the data isn't what you expect. It's never legal to have a list as a key for a dictionary. In the times that this worked, entitie wasn't a list, and then it failed when entitie became a list I'm trying to use SQLAlchemy to create a model which contains a one-to-many relationship.

I am using below code for updating an excel .xlsm) file and copying some values from it to some other positions in the same [HOST] i am using two functions for copying and pasting some required range of cells from one position to another and want to copy the 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) TypeError: unhashable type: 'dict' Using a Dictionary in a Set.
