Interpreter 5

A programming language that is designed to be easy for a computer to execute; also called machine language or assembly language.

Low-level language 6

Any one of the languages that people speak that evolved naturally.

Natural language 7

To examine a program and analyze the syntactic structure.

Parse 8

A property of a program that can run on more than one kind of computer.

Portability 9

An instruction that causes the Python interpreter to display a value on the screen.

Print statement 10

The process of formulating a problem, finding a solution, and expressing the solution.

Problem solving 11

A sequence of instructions that specifies to a computer actions and computations to be performed.

Program 12

A program stored in a file (usually one that will be interpreted).

Script 13

The structure of a program.
