importError ao tentar importar functools

Olá pessoal. Estou transcrevendo as aulas de Python Collections no PyCharm.

Meu código está assim:

from operator import attrgetter
from functools import total_ordering

@total_ordering
class ContaSalario:

    def __init__(self, codigo):
        self._codigo = codigo
        self._saldo = 0

    def passaMes(self):
        pass

    def __eq__(self, other):
        if type(self) != ContaSalario:
            return False

        return (self._codigo == outro.codigo and self._saldo == outro._saldo)

    def deposita(self, valor):
        self._saldo += valor

    def __str__(self):
        return (f'Conta = {self._codigo}, Saldo = {self._saldo}')

    def __lt__(self, other):
        if self._saldo < other._saldo:
            return self._saldo < other._saldo
        else:
            return self._codigo < other._codigo

Mas estou recebendo erro ao tentar importar o total_ordering:

/Users/rafaelviegas/PycharmProjects/Collections/venv/bin/python /Users/rafaelviegas/PycharmProjects/Collections/collections.py 
Traceback (most recent call last):

    from functools import total_ordering
ImportError: cannot import name 'total_ordering' from partially initialized module 'functools' (most likely due to a circular import) (/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/functools.py)

Podem me ajudar? Não consegui encontrar solução no StackOverflow ou no google.
