A lot of youtube vids use IDLE in their tutorial, there is absolutely nothing wrong with that. In matter of fact, it makes typing along easier if you use IDLE too, but situations like in the picture below piss me off!
So what happened in the second picture? Well, I used Python’s built in interpreter which you can open by simply typing python in the terminal. Look:
And I made the terminal’s background color transparent by changing it’s transparency. You do this by
Edit > Preferences
The following screen will appear, select the tab Appearance, in this tab you can change the transparency settings.
If you are finished with the interpreter but have other stuff to do in terminal, all you have to do is press CTRL d and the interpreter will close and you can do whatever you need to do in terminal.
