Definition of Scope. The scope of a variable, sometimes referred to as accessibility of a variable, refers to where the variable can be read from and/or written to, and the variable's lifetime, or how long it stays in memory.
There are names for functions, names for variables, and so on. When a name appears, it either defines the meaning of the name or refers to a definition elsewhere. The scope of a definition is the part of the program over which the definition holds. Every programming language has its own rules for determining scope. For example, in the following bit of Python, the second line refers to the x that was defined on the first line.
