我们使用一个字典method_dict来存储方法名和对应方法对象的映射关系。 在execute()方法中,我们首先解析字符串,然后获取对应的方法对象,并最终进行方法调用。 现在,我们可以创建一个DynamicMethodCaller的实例,并调用execute()方法来实现根据字符串动态调用方法的功能。 caller=DynamicMethodCaller()caller.execute("say_hello...
def dynamic_call(func, *args, **kwargs): return func(*args, **kwargs) def sample_func(a, b, c=None): return f"a: {a}, b: {b}, c: {c}" result = dynamic_call(sample_func, 1, 2, c=3) print(result) 这个例子展示了如何使用*args和**kwargs来动态调用一个函数,同时传递位置...

It is important to note that you arenot limited to functionsas decorators. A decorator may involve entire classes. The only requirement is that they must becallables. But we have no problem with that; we just need to define the__call__(self)method. ...
