Line of Code statistics tool

To make it easier to count the lines of your own code, you implemented the gadget in Python, which enables you to count multiple files in a single file and a directory, and output the number of lines of code, blank lines, and comment lines. For code in different languages, it is only necessary to modify its annotation to correctly count the number of lines of information.
