类'model‘没有实例方法'[ ]’

class Model:
    def __init__(self):
        self.data = []

    def __getitem__(self, index):
        return self.data[index]

# 错误的拼写
model = Model()
model.__getitem__(0)  # 这里应该是 __getitem__ 而不是 [ ]

# 正确的拼写
model.__getitem__(0)

# 创建实例并调用方法
model = Model()
print(model[2])  # 输出: 3
