使用self参数在循环中创建和调用自定义函数名

class MyClass:
    def __init__(self):
        self.functions = {}

    def create_functions(self, num):
        for i in range(num):
            def func(self, x):
                return x * i
            self.functions[f"func_{i}"] = func

    def call_functions(self, x):
        for name, func in self.functions.items():
            result = func(self, x)
            print(f"{name}({x}) = {result}")

# 创建对象
obj = MyClass()

# 创建5个函数
obj.create_functions(5)

# 调用函数
obj.call_functions(2)
