Python show-me-the-code No. 0007 Problem statistic code lines (comment, blank line, total number of rows) applet

No. 0007: There is a directory, which is your own written procedures, statistics on how many lines of code you have written. Include blank lines and comments, but be listed separately.

Train of thought: Get the directory, then traverse the directory of the code files, one by one to count each file code, and then the final summary of output.
