activecode |
A unique interpreter environment 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. Many modern languages first compile source code into byte code and then interpret the byte code with a program called 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 (or anyone reading the source code) 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 |
Another name for a runtime error |
|
|
executable |
Another name for object code that is ready to be executed |
|
|
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 |
|
|
high-level languages |
A programming language like Python that is designed to be easy for humans to read and write |
|
|
interpreter |
To execute a program in a high-level language by translating it one line at a time |
|
|
low-level languages |
A programming language that is designed to be easy for a computer to execute; also called machine language or assembly language |
|
|
natural language |
Any one of the languages that people speak that evolved naturally |
|
|
object code |
The output of the compiler after it translates the 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 |
A function used in a program or script that causes the Python interpreter to display a value on its output device |
|
|
problem solving |
The process of formulating a problem, finding a solution, and expressing the solution |
|
|
program |
A sequence of instructions that specifies to a computer actions and computations to be performed |
|
|
programming language |
A formal notation for representing solutions |
|
|
Python Shell |
An interactive user interface to the Python interpreter. The user of a Python shell types commands at the prompt (>>>), and presses the return key to send these commands immediately to the interpreter for processing |
|
|
runtime error |
An error that does not occur until the program has started to execute but that prevents the program from continuing |
|
|
semantic error |
An error in a program that makes it do something other than what the programmer intended |
|
|
semantics |
The meaning of a program |
|
|
shell mode |
A style of using Python where we type expressions at the command prompt, and the results are shown immediately. Contrast with source code, and see the entry under Python shell |
|
|
source code |
A program, stored in a file, in a high-level language before being compiled or interpreted. |
|
|
syntax |
The structure of a program |
|
|
syntax error |
An error in a program that makes it impossible to parse — and therefore impossible to interpret |
|
|
token |
One of the basic elements of the syntactic structure of a program; such as words, numbers, and chemical elements |
$ = not a legal token + = legal token |
|
structure |
the way the tokens are arranged |
