Python Test 1

PYTHON TEST 1 algorithm - CORRECT ANSWERS-A set of specific steps for solving a category of problems bug - CORRECT ANSWERS-an error in a program comment - CORRECT ANSWERS-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 token - CORRECT ANSWERS-basic elements of a language(letters, numbers, symbols) high-level language - CORRECT ANSWERS-A programming language like Python that is designed to be easy for humans to read and write. low-level langauge - CORRECT ANSWERS-A programming language that is designed to be easy for a computer to execute; also called machine language or assembly language print - CORRECT ANSWERS-A function used in a program or script that causes the Python interpreter to display a value on its output device. runtime error - CORRECT ANSWERS-An error that does not occur until the program has started to execute but that prevents the program from continuing. semantic error - CORRECT ANSWERS-An error in a program that makes it do something other than what the programmer intended. semantic - CORRECT ANSWERS-the meaning of a program syntax - CORRECT ANSWERS-The structure of a program syntax error - CORRECT ANSWERS-An error in a program that makes it impossible to parse — and therefore impossible to interpret. string - CORRECT ANSWERS-contains a string of letters variable - CORRECT ANSWERS-name that refers to a value assignment statement - CORRECT ANSWERS-gives value to a variable keyword - CORRECT ANSWERS-define the language's syntax rules and structure, and they cannot be used as variable names statement - CORRECT ANSWERS-instruction that the Python interpreter can execute operators - CORRECT ANSWERS-special tokens that represent computations like addition, multiplication and division modulus operator - CORRECT ANSWERS-%, works on integers (and integer expressions) and gives the remainder when the first number is divided by the second evaluate - CORRECT ANSWERS-To simplify an expression by performing the operations in order to yield a single value. int - CORRECT ANSWERS-A Python data type that holds positive and negative whole numbers float - CORRECT ANSWERS-A Python data type which stores floating-point numbers. Floating-point numbers are stored internally in two parts: a base and an exponent. When printed in the standard format, they look like decimal numbers flow of execution - CORRECT ANSWERS-The order in which statements are executed during a program run. function - CORRECT ANSWERS-A named sequence of statements that performs some useful operation. Functions may or may not take parameters and may or may not produce a result fruitful function - CORRECT ANSWERS-A function that returns a value when it is called. local variable - CORRECT ANSWERS-A variable defined inside a function. A local variable can only be used inside its function. Parameters of a function are also a special kind of local variable. parameter - CORRECT ANSWERS-A name used inside a function to refer to the value which was passed to it as an argument. boolean function - CORRECT ANSWERS-A function that returns a Boolean value. The only possible values of the bool type are False and True. None - CORRECT ANSWERS-A special Python value. One use in Python is that it is returned by functions that do not execute a return statement with a return argument. block - CORRECT ANSWERS-A group of consecutive statements with the same indentation. boolean expression - CORRECT ANSWERS-An expression that is either true or false. conditional statement - CORRECT ANSWERS-A statement that controls the flow of execution depending on some condition. In Python the keywords if, elif, and else are used for conditional statements. conditional statement - CORRECT ANSWERS-One program structure within another, such as a conditional statement inside a branch of another conditional statement type conversion - CORRECT ANSWERS-An explicit function call that takes a value of one type and computes a corresponding value of another type. definite iteration - CORRECT ANSWERS-A loop where we have an upper bound on the number of times the body will be executed. Definite iteration is usually best coded as a for loop increment - CORRECT ANSWERS-Both as a noun and as a verb, increment means to increase by 1. iteration - CORRECT ANSWERS-Repeated execution of a set of programming statements. nested loop - CORRECT ANSWERS-A loop inside the body of another loop. trace - CORRECT ANSWERS-To follow the flow of execution of a program by hand, recording the change of state of the variables and any output produced. aliases - CORRECT ANSWERS-Multiple variables that contain references to the same object. clone - CORRECT ANSWERS-To create a new object that has the same value as an existing object. Copying a reference to an object creates an alias but doesn't clone the object. compound data type - CORRECT ANSWERS-A data type that is itself made up of elements that are themselves values. decrement - CORRECT ANSWERS-To subtract one from a variable. dictionary - CORRECT ANSWERS-A collection of key/value pairs that maps from keys to values. exception - CORRECT ANSWERS-Raised by the runtime system if something goes wrong while the program is running
