+#arguments: One or more functions
+#return value: none
+#note： Decorators are implemented in such a way that the function being decorated is actually another function (the function name and other properties change).
+#To avoid this, Python's FuncTools package provides a decorator called wraps to remove such side effects.
+#When writing a decorator, it is a good idea to wrap FuncTools before implementing it.
+#It preserves the name and properties of the original function
