Could anyone please help me defining what does "is" do??

Question

i was typing this in the compiler and it returned as follows :
>>>1 is int
False
>>>"s" is str
False
. Why is that?! Shouldn't it print True instead??

Answer 1

"==" just checks for logical equality
"is" checks for two arguments referring to the same memory address (ergo to the same object)

1 == 1.0, but 1 points to an integer object, while 1.0 to a float, so 1 is not 1.0

a = [1, 2, 3] # one list object
b = [1, 2, 3] # another list object
c = a
a == b, but a is not b
a == c and (or *because*) a is c

Answer 2

If you want to test a condition use '=='

>>>1 == int
True
>>> "s" == str
True
