Why does Python behave like this?

>>> a = "Early morning"
>>> a is "Early morning"
False
>>> a = "Early_morning"
>>> a is "Early_morning"
True

Implementation can cache string objects if it chooses so. If you really need to compare strings with is (and you don't) do it like this:

>>> a = "Early morning"
>>> a is "Early morning"
False
>>> import sys
>>> sys.intern("Early morning") is a
True
