This error occurs when trying to hash a list, which is an unhashable object. For example, using a list as a key in a Python dictionary will cause this error since dictionaries only accept hashable data types as a key. The standard way to solve this issue is to cast a list to a tuple, which is a hashable data type.
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, use a frozenset instead, or convert the dictionary into a JSON string before using it as a key.
TypeError: unhashable type: 'list' usually means that you are trying to use a list as an hash argument. This means that when you try to hash an unhashable object it will result an error. For ex. when you use a list as a key in the dictionary , this cannot be done because lists can't be hashed.
The message “TypeError: unhashable type” appears in a Python program when you try to use a data type that is not hashable in a place in your code that requires hashable data. For example, as an item of a set or as a key of a dictionary.
data is suppossed to be a "a buffer in the standard application/x-www-form-urlencoded format.", not a dict.
Before you pass the data dict in do data = urllib.urlencode(data), so you get the correct format from your dict.
