Python Statistics code Total rows (lines of code, blank lines, comment lines)

In the process of working or learning code, we often want to know how many lines of code we have written, and today we write a script in the project environment to count the number of project code.

Function:

1. Total number of statistics code rows

2. Counting Empty rows

3. Count the number of comment lines
