- problem solving:
- The process of formulating a problem, finding a solution, and expressing the solution.
- high-level language:
- A programming language like Python that is designed to be easy for humans to read and write.
- low-level language:
- A programming language that is designed to be easy for a computer to execute; also called “machine language” or “assembly language.”
- portability:
- A property of a program that can run on more than one kind of computer.
- interpret:
- To execute a program in a high-level language by translating it one line at a time.
- compile:
- To translate a program written in a high-level language into a low-level language all at once, in preparation for later execution.
- source code:
- A program in a high-level language before being compiled.
- object code:
- The output of the compiler after it translates the program.
- executable:
- Another name for object code that is ready to be executed.
- prompt:
- Characters displayed by the interpreter to indicate that it is ready to take input from the user.
- script:
- A program stored in a file (usually one that will be interpreted).
- interactive mode:
- A way of using the Python interpreter by typing commands and expressions at the prompt.
- script mode:
- A way of using the Python interpreter to read and execute statements in a script.
- program:
- A set of instructions that specifies a computation.
- algorithm:
- A general process for solving a category of problems.
- bug:
- An error in a program.
- debugging:
- The process of finding and removing any of the three kinds of programming errors.
- syntax:
- The structure of a program.
- syntax error:
- An error in a program that makes it impossible to parse (and therefore impossible to interpret).
- exception:
- An error that is detected while the program is running.
- semantics:
- The meaning of a program.
- semantic error:
- An error in a program that makes it do something other than what the programmer intended.
- natural language:
- Any one of the languages that people speak that evolved naturally.
- formal language:
- Any one of the languages that people have designed for specific purposes, such as representing mathematical ideas or computer programs; all programming languages are formal languages.
- token:
- One of the basic elements of the syntactic structure of a program, analogous to a word in a natural language.
- parse:
- To examine a program and analyze the syntactic structure.
- print statement:
- An instruction that causes the Python interpreter to display a value on the screen.
