Python show-me-the-code No. 0007 Question code statistics

question No. 0007: There is a directory, which is the program you wrote yourself, to count how many lines of code you have written. Include blank lines and comments, but are listed separately.

Idea: Get the directory, and then walk through the directory of code files, counting each file's code, and then finally summarizing the output.
