It looks like after upgrading the code for /usr/bin/command-not-found to Python
3 that the zsh function was not.

Actual Results:
---------------
~ >> foo
  File "/usr/bin/command-not-found", line 14
    print(file=sys.stderr)
              ^
SyntaxError: invalid syntax

~ >> 

Expected Results:
-----------------
~ >> foo
  foo: command not found

~ >>


In /etc/zsh_command_not_found, within the command_not_found_handler function it
reads:

line 5:  if [ -x /usr/bin/python ] && [ -x /usr/bin/command-not-found ]; then
line 9:    /usr/bin/python /usr/bin/command-not-found "${(Q)1}" zypp

when it should be:

line 5:  if [ -x /usr/bin/python3 ] && [ -x /usr/bin/command-not-found ]; then
line 9:    /usr/bin/python3 /usr/bin/command-not-found "${(Q)1}" zypp
