Import python to bash

I try to call the Python script from bash in Ubuntu 16. I want the word "start" printed from python.

bash

#!/bin/bash echo "hello world" set -e set -u dir=`"/home/myname/foo.py"` echo directory = $dir 

python

 # !/usr/bin/python3 # -*- coding: utf-8 -*- st = "start" print(st) class Moo(object): def __init__(self): pass def start(self): return "string from FOO.py" 

terminal

 myname@ubuntu:~$ ./new_bash.sh hello world /home/myname/foo.py: строка 3: st: команда не найдена /home/myname/foo.py: строка 4: ошибка синтаксиса около неожиданной лексемы `st' /home/myname/foo.py: строка 4: `print(st)' 

Why it happens?
