In Python, a "variable" is a name given to an object. In Python, the "=" sign is used to assign a name to an object: the name is on the left-hand side, and the object is on the right hand side. Multiple names can be assigned to the same object. In the example you gave, "a" is a name given to the object "10" which is an integer. If you do: a = 10 b = a a = "hello" b will be 10. b was just another name given to object 10 to which the name "a" was referring to at that point, even though we decided later that a should refer to the string "hello" (which is an object).
