$ strace ./python -c '' 2>&1 | grep -c stat Python 2.7 - 161 stats Python 3.2 - 555 stats Python 3.3 - 243 stats
This will probably depend on the length of sys.path:
$ strace -e stat python2.7 -Sc "" 2>&1 | wc -l 35 $ strace -e stat python3.2 -Sc "" 2>&1 | wc -l 298 $ strace -e stat python3.3 -Sc "" 2>&1 | wc -l 106
$ strace -e stat python2.7 -c "" 2>&1 | wc -l 200 $ strace -e stat python3.2 -c "" 2>&1 | wc -l 726 $ strace -e stat python3.3 -c "" 2>&1 | wc -l 180
