How to enter interactive mode?
I read the instructions under documentation, but I'm still confused. How do you enter interactive mode?
If you mean the interactive Python console, you can get there by swiping left in the editor.
I'm guessing you're reading the Pythonista documentation in a browser? Pythonista also has a built-in documentation viewer, which you can open with the "?" button in the console toolbar.
I am on the iPad, does that matter? How do I enter the editor? I’m very confused by the app in general.
Once you see it you will understand.
Get to where you can see the program lines of a file. Create a new program if you need a place to start. Touch the screen to bring up the keyboard. Now, swipe left, you will now see that you are in the "console" with the keyboard still showing. But now there is an extra line right above the keyboard. This line has the greater than sign (>) on the left with a blinking vertical line as input.
Now you can enter simple stuff like "2+2" and other python stuff. Way simple and fun.
This is awesome and you have fun
"Interactive mode" = the Console, which is available whenever you're in documentation as a separate tab.
