Before you keep reading...
Runestone Academy can only continue if we get support from individuals like you. As a student you are well aware of the high cost of textbooks. Our mission is to provide great books to you for free, but we ask that you consider a $10 donation, more if you can or less if $10 is a burden.
Before you keep reading...
Making great stuff takes time and $$. If you appreciate the book you are reading now and want to keep quality materials free for other students please consider a donation to Runestone Academy. We ask that you consider a $10 donation, but if you can give more thats great, if $10 is too much for your budget we would be happy with whatever you can afford as a show of support.
A unique interpreter environment that allows Python to be executed from within a web browser.
A general step by step process for solving a problem.
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.
An interactive environment that allows the user to control the step by step execution of a Python program
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.
To translate a program written in a high-level language into a low-level language all at once, in preparation for later execution.
The process of finding and removing any of the three kinds of programming errors.
Another name for a runtime error.
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 language¶
A programming language like Python that is designed to be easy for humans to read and write.
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; 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.
To examine a program and analyze the syntactic structure.
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.
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.
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.
The structure of a program.
- syntax error¶
An error in a program that makes it impossible to parse — and therefore impossible to interpret.
One of the basic elements of the syntactic structure of a program, analogous to a word in a natural language.
