1 < -1 == 3 > 4 evaluates to False. Why?
It must evaluate to true according to operator precedence. As 1<-1 evaluates to false and 3 > 4 also evaluates to false. Then False == False is True. But why does it evaluate to Fasle?

Python allows chaining of logical operators. So
1 < 3 > 2
in other languages will be
true > 2, which is false
But in Python, it will be
1 < 3 and 3 > 2, which is True
Similarly,
1 < -1 == 3 > 4
is equivalent to
1 < -1 and -1 == 3 and 3 > 4, which is False

As per the explanation of XXX, here is another way of looking it.
print((1 < -1) == (3 > 4)) # true
