a,b = "wtf!", "wtf!"
a is b # This returns False

I've just checked this and found that the behavior was changed in Python 3.7.

$ python2.7 -c 'a, b = "wtf!", "wtf!"; print(a is b)'
True
$ python3.6 -c 'a, b = "wtf!", "wtf!"; print(a is b)'
True
$ python3.7 -c 'a, b = "wtf!", "wtf!"; print(a is b)'
False
