" This really is termed binding the identify to the thing. For the reason that name's storage place will not include the indicated value, it is incorrect to contact it a variable. Names could be subsequently rebound Anytime to objects of considerably various styles, together with strings, procedures, intricate objects with knowledge and strategies, etcetera. Successive assignments of a typical benefit to a number of names, e.g., x = two; y = two; z = two result in allocating storage to (at most) three names and a single numeric item, to which all three names are bound. Since a reputation is a generic reference holder it is actually unreasonable to find out here now associate a hard and fast data form with it. However in a given time a name will likely be sure to some item, which is able to have a type; thus There's dynamic typing.
