[index1:index2 ] is list slice operation, which will not work on dict. You can't add like this, it's a dictionary that takes key and value as a separate entity like. After doing this, the dictionary will automatically convert itself like- 1 Answer. Sorted by: 1. Since [HOST] is really for simple logical operations, you cannot access Series methods of columns. As workaround, consider assign of flags to then query against. Consider also [HOST]e for regex clean. df_dict[key] = What causes a TypeError: unhashable type: ‘dict_keys’?

OR A container of (node, attribute dict) tuples. Node attributes are updated using the attribute dict. Each element in your list E is a tuple containing one node and 4 dicts, while add_nodes_from only accepts a single dict. Those 4 dicts should be merged into a single dict: {'a': i, 'b': j, 'c': k, 'd': l} 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)]) TypeError: format requires a mapping TypeError: unhashable type: 'dict' TypeError: not enough arguments for format string python; Share.

Solution for TypeError: Unhashable Type ‘Dict’ Exception in Python. 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 new dictionary (new_dict) using a tuple (1, 'example') as a hashable key and associates it with the nested_dict 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
