How "is" is work in python?
I'm tryin to understand how "is" does work, so I code this lines and examine the results? -If I assign two variables "a, b" the same values, I get (a is b )----> True -If I change their values I get False So I conclude with: -If a and b having the same value so they point at same object "based on the function of "is" as I read on the net', and vice versa My question is: am I right in my conclusion??

No. Its all about the memory address. If it's the same address, they are the same. If not, then they arent

It is related to memory locations . I meant it will check if the memory location is same as checked or not

Saad Khan I don't think so, it is all about 'pointers'

“is” operator can be used to efficiently check for the equality of two string objects. The is operator returns True if the two variables point to the same data object, Else, returns False
"==" operator compares the string in a character-by-character manner and returns True if the two strings are equal, otherwise, it returns False

Your question is really Hilarious, but let me tell you something, like you say ' something is equal to that thing' in the same way 'is' works in python. It is always preferred to use operators like !,= etc.
