How to run ubuntu python3.4 executable?

Question

Python

Good afternoon!
I am using ubuntu 14.10 + python 3.4.
The file does not want to run at all:

#! /usr/bin/ python3.4
print('Hi')

Assigned it to be executable, checked the address of the interpreter.

Answer 1

#!/usr/bin/env python3.4
Then you do it yourself

chmod u+x script.py
./script.py

Answer 2

#! /usr/bin/ python3.4
Why spaces?
#!/usr/bin/python3.4
