I can't tell exactly what went wrong with what you did because there are formatting issues with your post -- you need to indent the code 4 spaces when you ask the question to make it look right, which effects the meaning because Python is sensitive to white space.

I modified your text and got it to work for me

from ipywidgets import interact

def myfunction(arg): 
    return arg+1 

interact(myfunction, arg=9)
