Check if list contains only item x

Question

Say all of w, x, y, and z can be in list A. Is there a shortcut for checking that it contains only x--eg. without negating the other variables?

w, x, y, and z

Answer 1

I'm not sure what without negating the other variables means, but I suspect that this is what you want:

if all(item == x for item in myList): 
    #do stuff
