Chapter2 Variables Expressions Statements Pdf Variable Computer An expression is a combination of values, variables, operators, and calls to functions. if you type an expression at the python prompt, the interpreter evaluates it and displays the result:. Variables •a variable is a named place in the memory where a programmer can store data and later retrieve the data using the variable “name” •programmers get to choose the names of the variables •you can change the contents of a variable in a later statement x12.2 y14 x = 12.2 y = 14.
