Python Forum

I'm using Linux Mint 19.1
I've alt-installed python 3.7.4 and 3.8.0
"idle3 is already the newest version (3.6.7-1~18.04)"

Whenever I launch IDLE it starts with:
Python 3.6.8 (default, Oct 7 2019, 12:59:55)

How to run my script with Python 3.8 using IDLE?

Try typing in a terminal

Output:
python3.8 -m idlelib

print("You are marvellous")
while True:
. . . . print("Thaaaaank Youuuuuu")

I've created a desktop launcher also....
