F-String not working when in IDLE editor

[nadimsarrouh]

Hello everyone,

i am a complete python beginner, so I have a very basic question that i couldn't resolve on my own.

I am trying to make use of f-string. I have the newest IDLE version installed on a mac (Python 3.7.2). I wrote the following script, named f.py:

name = "Eric"
age = 74
f"Hello, {name}. You are {age}."

If I run this script I get nothing displayed in the shell, not even an error message. Just the restart message

================ RESTART: /Users/nadim/Documents/python/f.py ================
>>> 

If I however enter these three lines directly in the shell it works like a charm.

>>> name = "Eric"

>>> age = 74

>>> f"Hello, {name}. You are {age}."

'Hello, Eric. You are 74.'

I really would like to use f-strings in my scripts, but can't seem to get it working. Does anybody have an idea?
