Python and Sublime: can't open file

Question

I have recently downloaded Sublime 3. It was working fine for few days, but today, while trying to do a project, it was giving me an error.

So I did the simple 'Hello world' printing and it still gave the error:

print("Hello World")

Error: Sublime text 3

I also tried changing the environmental variables and tried to resintall Sublime, but it didn't worked.
