Dear all, I have a question concerning the output of the id() function. In particular since is should: "" Return the identity of an object. This is guaranteed to be unique among simultaneously existing objects. (Hint: it's the object's memory address.) "" i expect that for two differnt objects it returns two differnt adress in memory.
Let's seee a correct case: >>> a=10 >>> b=20 >>> a is b False >>> id(a) 9986060 >>> id(b) 9985940 >>> c=a >>> c is a True >>> id(c) 9986060 >>> id(a) 9986060 And now a strange (for me) output: >>> d=10 #here i'm assingning a integer value to a fresh new variable d without any kind of #link to the variable a >>> d is a True >>> d==a True >>> id(a) 9986060 >>> id(d) 9986060 But if I chose as a value another number (a big one, let say 1e10) I get what I will expect also in the case of the chose of the integer 10 showed above: >>> a=1e10 >>> d=1e10 >>> d is a False >>> id(a) 11388984 >>> id(d) 11388920 >>> can you please explain me the reasion of this strange behaviour.
