Turtle Graphic Window not working from VSCode

I am using Visual Studio Code as my IDE and I am a bit of a beginner with Python so I decided to try out the turtle library built into Python to learn some of the syntax. However, when I tried running just a simple script to see if it would work, the window flashed open for less than a second then closed. I have tried using different extensions and redownloading the python extension for VSCode. This is my code I'm trying to run:

import turtle
geoff = turtle.Turtle()

geoff.forward(100)

Please help as I really can't figure out why the window won't stay open. Thanks!
