Creating an interactive menu (Python)

[kurrocap]

I’m currently making an automatic watering system using relays, servos, and a raspberry pi, and this video proved very helpful, thank you!

I’m going to create a menu in which you can view the last time watered, and specific zone watering

If it wasn't for the flickering blocks of black from time to time, this would have been a good video. How ever, I would encourage the maker of this video to make a new video and take this down.

Blinking bars on top portion of the screen render this video practically unwatchable.

You need a new Graphics Card Pal, that Blinking on your screen is very annoying.

For me the error is like 11:35 it says "NameError: name 'Mikkel' is not defined". If I enter Mikkel in betwee quotes, it works. So, somehow, it is not interpreting the input value as a "string", it is interpreting it as a "script variable". Why is this happening if I wrote everything just like it is shown in this video? (different versions of Python maybe?)
