= Decorator (func), Decorating and returning the Func function. Looking at our adorner function- decorator, the function's incoming parameter is func (decorated function), and the return parameter is an inner function. The inner layer function here-wrapper, in fact, is equivalent to the closure function, which plays the role of decorating a given function, the wrapper parameter is *args, **kwargs. The arguments represented by *args are passed in as a list, and the parameters represented by **kw

Enter a string ending with #, which requires filtering out all non-hexadecimal characters (not case), forming a new string representing a hexadecimal number, and then converting it to a decimal number after the output. If the first character of the filtered string is "-", it indicates that the number is negative.Input format:The input gives a non-empty string that ends with # in a row.Output format:Outputs the converted decimal number in a row.

Static keyword usage in Java:1, static member variable: All objects share one copy. It can be called with the class name, or it can be called with the object name.2, static function: can be called with the class name, or can be called with the object name. Note, however, that non-static member variables cannot be used inside a function. Because a non-static member variable is related to an object, the static function does not recognize which object it is.3, Static code block: The followingclass

values of PA and PB are the same, which is the address of variable A, that is, two pointers point to the same variable.It is worth noting that although the two pointers to the same variable are syntactically legal, they should be avoided in actual development. With a little attention, this code can be confusing. Continue with the above example:output PA points to the data, for 1982coutEndl; 1003; output PA-directed data again, and become 1003cout If we just look at the output of this pro
