Formatting in python

Question

I am currenty teaching myself Python using the book called Learn Python 3 the Hard Way. I've reached to exercise 14 (Prompting and Passing) and I have some code which needs to be displayed in PowerShell but something is not working here. I'll post the code below following the explanation.

from sys import argv

script, user_name = argv
prompt = '>'

print (f"Hi {user_name}, I'm the {script} script.")
print ("I'd like to ask you a few questions.")
print (f"Do you like me {user_name}?")
likes = input(prompt)

print (f"Where do you like {user_name}?")
lives = input(prompt)

print(f"What kind of computers do you have?")
computer = input(prompt)

print(f"""
Alright, so you said {likes} about liking me.
You live in {lives}. Not sure where that is.
And you have a {computer} computer. Nice.
""")

So, PowerShell won't print nothing because I receive the following error:

File "14.py", line 6
    print (f"Hi {user_name}, I'm the {script} script.")
                                                 ^
SyntaxError: invalid syntax

I can't find the solution. I know it's because of string formatting which doesn't work and I previously had another exercise with string formatting but I've managed to go around the error and print what I wanted. But still, it's annoying and I'm trying to find the answer. Could someone give me a hint?

Fstrings were introduced in 3.6. If you're using an earlier version than that, they will not work. — khelwood, Jul 29 '18 at 15:43
Python 3.4.... I've just read in the book that the author used Python 3.6 to run the exercises. Maybe that's the issue. — onemindwork, Jul 29 '18 at 15:45
You should seriously consider switching to a tutorial that teaches you the easy way. And python 3.6 or 3.7 of course. — Andras Deak -- Слава Україні, Jul 29 '18 at 15:45
how did you run the script? Seems like it needs 2 argument values. — Orcun, Jul 29 '18 at 15:46
Andras Deak, why do you say that? Is it too hard or just not productive? — onemindwork, Jul 29 '18 at 15:49
There are many users who are confused by the structuring and style of the tutorial and end up with a skewed or wrong view of how python works. There's no magic in python but that book can make it unnecessarily hard for new users to see the simplicity. — Andras Deak -- Слава Україні, Jul 29 '18 at 15:51
