How to Think Like a Computer Scientist

TermDefinition
activecode a unique interpreter that allows Python to be executed from within a web browser
algorithm a general step by step process for solving a problem
bug an error in a program
byte code an intermediate language between source code and object code, typically interpreted by a virtual machine
codelens an interactive environment that allows the user to control the step by step execution of a Python program
comment information in a program that is meant for other programmers and has no effect on the execution of the program
compile to translate a program written in a high-level language into a low-level language all at once, in preparation for later execution
debugging the process of finding and removing any of the three kinds of programming errors
exception a runtime error
executable object code that has been compiled
formal language any one of the languages that people have designed for specific purposes; all programming languages
high-level language a programming language like Python that is designed to be easy for humans to read and write
interpret to execute a program in a high-level language by translating it one line at a time.
low-level language a programming language that is designed to be easy for a computer to execute; machine language or assembly language
natural language any one of the languages that people speak that evolved naturally
object code the output of the compile after it translates a program
parse to examine a program and analyze the syntactic structure
portability a property of a program that can run on more than one kind of computer
print function used by a program or script that causes the Python interpreter to display a value on its output device
problem solving process of formulating a problem, finding a solution, and expressing the solution
program sequence of instructions that specify to a computer actions and computations to be performed
programming language formal notation for representing solutions
Python shell interactive user interface to the Python interpreter
runtime error error that does not occur until the program has started to execute but that prevents the program from continuing
semantic error error in a program that makes it do something other than what the programmer intended; logic error
semantics meaning of a program
shell mode style of using Python where we type expressions at the command prompt, and the results are shown immediately.
source code program, stored in a file, in a high-level language before being compiled or interpreted.
syntax the structure of a program
syntax error error in a program that makes impossible to parse - and therefore impossible to interpret
token one of the basic elements of the syntactic structure of a program, analogous to a word in a natural language

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
