get format on int for awk print

Question

I want the number of lines of my python files with relative path.

I get that like this::

$ find ./ -name "*.py" -exec wc -l {} \;| awk '{print $1, $2}'
29 ./setup.py
28 ./proj_one/setup.py
896 ./proj_one/proj_one/data_ns.py
169 ./proj_one/proj_one/lib.py
310 ./proj_one/proj_one/base.py
0 ./proj_one/proj_one/__init__.py
72 ./proj_one/tests/lib_test.py

How could I get (formated ints) like this::

 29 ./setup.py
 28 ./proj_one/setup.py
896 ./proj_one/proj_one/data_ns.py
169 ./proj_one/proj_one/lib.py
310 ./proj_one/proj_one/base.py
  0 ./proj_one/proj_one/__init__.py
 72 ./proj_one/tests/lib_test.py

You can use printf with a width format modifier to make a formatted column:

$ find ./ -name "*.py" -exec wc -l {} \;| awk '{printf "%10s %s\n", $1, $2}'

On most platforms, you can print with comma separators as a specifier (if you have BIG files) but the quoting can be challenging for command line use:

$ echo 10000000 | awk '{printf "%'\''d\n", $1}'
10,000,000
