Question

How do I calculate the number of lines written in a project containing multiple sub dirs in a python project. for example a dir structure is like

A  
 \ <*some files here*>\  
  B  
   \ <*some files here*>\ ... and so on...

Answer 1

You could use the find utility in linux.

On the command prompt:

$ find <project_directory_path> -name '*.py' | xargs wc -l

This will give you the count of all files ending with .py in the project_directory and finally the total. (I am assuming you just want the count of .py files)

If you just want the total and nothing else, you could use:

$ find <project_directory_path> -name '*.py' | xargs wc -l | tail -1
