Hello all,

I am working on creating my own On-Screen Keyboard and I have all of the buttons figured out aside from the backspace button. Does anyone know how I could make this button delete the very last character of my text field on action performed? I tried using len() and cutting it that way but that didn't seem to work as it cannot include both unicode and int.

Thanks in advance.

Or, just use the resource. 🙂

Strings are iterables, so you can use slicing to achieve your purpose.

```auto
test = 'myString'
newString = test[:-1]
print newString

```

They are there. I see you marked as solved, but I would spend the time to learn how they present resources so you will know for next time.
