Digital Literacy Computer Basics Computer Languages Programming Paradigms - Part 1

I'm doing the first challenge in Computer Basics and I am unable to preview my work at this time. I click the button and

the screen that simulates Workspaces goes black. When I click the editor button the code I wrote shows up again. How do I fix this problem if it happens again?

HelloWorld.py 
print("Hello MELISSA BROWN")

Try the 'Check Work' button. It will submit the answer and tell you if you got it right. If it's right you'll continue on, if not it will keep asking you to try again until you get it.

It's not as handy as when the preview works, but this will get you through the challenge.

Thank you for responding, Matthew.

I did just as you suggested (in part because I figured I didn't have anything to lose) and, fortunately, I had the right answer and could go on from there, without any other problems.

Sometimes clicking the "check work" button fixes, other times depending on the issue the preview will not pick it up.

Thank you for responding, Caleb.

Clicking the "check work" button did work.
