How to recursively traverse a directory tree and count the number of lines in all .py files?

Question

bash

Good afternoon. It is necessary to somehow calculate the number of lines of code in the project, I can’t figure out how to do it. Trying to build a command for bash from ls, find, wc, grep but nothing comes up. For example, there is a directory structure like this:

.
├── 1.py
├── 2.py
└── folder
    └── 3.py

Tell me how to calculate the total number of lines in .py files?
Thank you.

Answer 1

find -name '*.py' | xargs wc -l
The last line will be the total number of lines.
You can do this:
find -name '*.py' | xargs cat | wc -l
