Take care with the directionality of those statements. In Python we don't give the name *to* the object, which would imply that the object “has” that name in some sense. The object is totally unaffected, and assignment does not give the object any knowledge about that name. We also don't assign names *to* objects; if anything, we assign the object to the name. It is the name that “has” the object. Or perhaps less confusingly, the name is *bound to* the object. It is frequently a point of confusion that assignment *never* affects the object, so it's best to avoid giving that false impression. > In the example you gave, "a" is a name given to the object "10" which > is an integer. Rather, I'd prefer to say that ‘a’ now refers to the object ‘10’. The object ‘10’ was not “given” anything. -- \ “When I get new information, I change my position.
