1.Input: A program gets data, perhaps from a file, keyboard, touchscreen,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\




|\ network, etc. |\




2.Process: A program performs computations on that data, such as
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\




adding two values like x + y
|\ |\ |\ |\ |\ |\




3.Output: A program puts that data somewhere, such as to a file,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\




screen, or network. |\ |\




4.computational thinking,: creating a sequence of instructions to solve a |\ |\ |\ |\ |\ |\ |\ |\ |\ |\




problem

5.algorithm: A sequence of instructions that solves a problem
|\ |\ |\ |\ |\ |\ |\ |\




6.Python interpreter: a computer program that executes code written in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\




the Python programming language.
|\ |\ |\




7.interactive interpreter: a program that allows the user to execute one line
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\




|\ of code at a time

,10.prompt: indicates the interpreter is ready to accept code
|\ |\ |\ |\ |\ |\ |\ |\




11.statement: a program instruction |\ |\ |\




12.Expressions: code that return a value when evaluated |\ |\ |\ |\ |\ |\ |\




13.cariables: named references to values stored by the interpreter
|\ |\ |\ |\ |\ |\ |\ |\




14.print(): function that displays variables or expression values
|\ |\ |\ |\ |\ |\ |\




15.'#": character tha denote comments, which are optional but can
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\




be used to explains portions of code to a human reader
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\




16.string literal: text enclosed in quotes (single or double) and can
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\




contain letters, numbers, spaces, or symbols
|\ |\ |\ |\ |\




17.Why would a programmer add
|\ |\ |\ |\

|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\




variable

|\ |\ |\ |\ |\ |\




23.int(): converts a string to an integer
|\ |\ |\ |\ |\ |\

, symbols can be combined to create a program
|\ |\ |\ |\ |\ |\ |\




25.runtime error: program's syntax is correct, but the program attemps
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\




an impos- sible operation, such as dividing by zero or multiplying
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\




strings together |\




26.crash: Abrupt and unintended termination of a program
|\ |\ |\ |\ |\ |\ |\




27.SyntaxError: The program contains invalid code that cannot be
|\ |\ |\ |\ |\ |\ |\ |\ |\




understood.

28.IndentationError: The lines of the program are not properly indented.
|\ |\ |\ |\ |\ |\ |\ |\ |\




29.ValueError: An invalid value is used- can occur if giving letter to int().
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
