Question 1

Algorithm

Answer 1

A general store by step process for solving a problem

Question 2

Bug

Debugging

Answer 6

The process of finding and removing any of the three kinds of programming errors

Question 7

Exception

Answer 7

Another name for a runtime error

Question 8

Executable

Answer 8

Question 9

Formal language

Answer 9

Any one of the languages that prior have designed for specific purposes such as representing mathematical ideas or computer programs. All programming languages are formal languages

High level language

Answer 10

A programming language like Python that is designed to be easy for humans to write and read

Question 11

Interpret

Answer 11

To execute a program in a high level language by translating it line by line

Question 12

Low level language

Answer 12

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

Question 13

Natural language

Answer 13

Any one of the languages that people speak that evolved naturally

Question 14

Object code

Answer 14

The output of the compiler after it translates the program

Question 15

Parse

Answer 15

To examine a program and analyze the syntactic structure

Question 16

Portability

Answer 16

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

Question 17

Answer 17

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

Question 18

Program

Answer 18

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

Question 19

Programing language

Answer 19

a formal notation for representing solutions

Question 20

Python shell

Answer 20

an interactive user interface to the Python language

Question 21

runtime error

Answer 21

Question 23

semantics

Answer 23

the meaning of a program

Question 24

shell mode

Answer 24

a style of using Python where we type expressions at the command prompt, and the results are shown immediately. Contrast with source code

Question 25

Answer 25

a program, stored in a file, in a high-level language before being compiled or interpreted

Question 26

syntax

Answer 26

the structure of a program

Question 27

syntax error

Answer 27

an error in a program that makes it impossible to parse, and therefore impossible to interpret

Question 28

token

Answer 28

one of the basic elements of the syntactic structure of a program, analogous to a word in a natural language
