Types tell Python what operations you can do with the objects. Expressions evaluate to one value and involve objects and operations. Variables bind names to objects. Programs only do what you tell them to do. Lines of code are executed in order. Good variable names and comments help you read code later. YOU TRY IT! What’s the value of s1 and s2?
Input is any data and instructions entered into the memory of a computer. Instructions can be entered into the computer in the form of programs, commands, and user responses. Program: A series of related instructions that tells a computer what tasks to perform and how to perform them.
This handout will reference variables and data types to explain the concepts of input and output in Python. For more information about variables and data types, please refer to the Academic Center for Excellence’s Python: Variables and Data Types handout.
This will show how the data items will be put into the ! arrays that are passed to the Input Processor "Get" (GetObjectItem) routines. ! All alpha fields are limited to 100 characters.
tasks are position, text, select, and quantify. The unit of information that is input in a position interaction task is of course a position; the text task yields a text string; the select task yields
Standard input is input entered interactively on the terminal The end of standard input is signalled using the end-of-file (EOF) character (<ctrl-d>) Example (a typical Python program receiving standard input):
An indirect input device is one which does not provide input in the same physical space as the output. Indirect devices eliminate occlusion of the screen by the user's hand and fingers.
