方法1:

class_name = "MyClass"
method_name = "MyMethod"

obj = globals()[class_name]()
getattr(obj, method_name)()

方法2:

eval("MyClass().MyMethod()")

補充:

模組載入( full_class_name :完整名稱 如 app.MyClass )

def load_class(full_class_name):
    cls = None
    if full_class_name in globals():
        cls = globals()[full_class_name]
    else:
        if "." in full_class_name:
            import importlib

            module_name, cls_name = full_class_name.rsplit('.', 1)
            mod = importlib.import_module(module_name) #importlib 可在runtime 時動態載入 package
            cls = (getattr(mod, cls_name))

    return cls
