Incomprehensible behaviour
Hi
I've got a function, which returns True or False: (mission Words Order)
words_order=lambda t,w:w==[*(s:=set(w))]and s<=set(t:=t.split())and(a:=[*map(t.index,w)])==sorted(a)
The problem is that it gives different results for the same input. I assume, the problem hides in here
w==[*(s:=set(w))]
but I don't understand why it is equality sometimes and the other times not
Any help is greatly appreciated!
