Consider that each named variable is a pointer to a memory location that holds a value. This is one of the ways in that a typed compiled language and an untyped scripted language may differ in their treatment of data items (or variables). Consider the following C and Python code: C: int a, b; b = 6; a = b; In C, this places the numeric value 6 into the memory location identified by the variable "b", then copies the value from the location pointed to by "b" into the location pointed to by "a". b is a pointer to a memory location containing the value 6 a is a pointer to another memory location also containing the value 6 Python: b = 6 a = b In Python, this first puts the value 6 in in a memory location and points "b" at that memory location, then makes "a" point to the same memory location as "b" points to. b is a pointer to a memory location containing the value 6 a is a pointer to the same memory location Do you understand the difference? -- Denis McMahon, denismfmcma...@gmail.com -- http://mail.python.org/mailman/listinfo/python-list
