When a program that runs in an interpreter has some of its files deleted,
"zypper ps" shows the interpreter instead of the actual program.
Showing the program that's being executed is more useful for deciding if the
machine warrants a reboot.

For example, after an update to Python 3.6, zypper ps shows:

5857  | ... | python3.6 (deleted)           |         |
/usr/lib64/libpython3.6m.so.1.0
25325 | ... | python3.6 (deleted)           |         |
/usr/lib64/libpython3.6m.so.1.0
25332 | ... | python3.6 (deleted)           |         |
/usr/lib64/python3.6/lib-dynload/_heapq.cpython-36m-x86_64-linux-gnu.so

While ps shows those 3 processes to be, in order:

5857   ...  \_ /usr/bin/python3 /usr/bin/chrome-gnome-shell
25325  ...  \_ /usr/bin/python3 /usr/bin/blueman-applet
25332  ...  \_ /usr/bin/python3 /usr/bin/blueman-tray


Even if there's no general solution for detecting interpreters, hard-coding the
detection of the most common system-wide interpreters (Bash, Python, Ruby,
Perl) would still be very useful.
