Rename Method allows rename functions using datamodels function names

Steps to reproduce the behavior:

1. Code before refactoring:

class Soma:
    def __init__(self, a, b):
        self.a = a
        self.b = b

    def total(self):
        return self.a + self.b

s = Soma(2, 3)
print(s.total())
print(s)

2. Apply the rename method to Soma.total

3. Code after refactoring:

class Soma:
    def __init__(self, a, b):
        self.a = a
        self.b = b

    def __str__(self):
        return self.a + self.b

s = Soma(2, 3)
print(s.__str__())
print(s)
