PYTHON -DATA SCIENCE TEST WITH VERIFIED SOLUTIONS #12
Algorithm - correct answer A set of specific steps for solving a category of problems
Bug - correct answer an error in a program
Comment - correct answer 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 answer basic elements of a language(letters, numbers, symbols)
High-level language - correct answer A programming language like Python that is
designed to be easy for humans to read and write.
Low-level langauge - correct answer A programming language that is designed to be
easy for a computer to execute; also called machine language or assembly language
Print - correct answer A function used in a program or script that causes the Python
interpreter to display a value on its output device.
Runtime error - correct answer An error that does not occur until the program has
started to execute but that prevents the program from continuing.
Semantic error - correct answer An error in a program that makes it do something other
than what the programmer intended.
Semantic - correct answer the meaning of a program
Syntax - correct answer The structure of a program
Syntax error - correct answer An error in a program that makes it impossible to parse —
and therefore impossible to interpret.
String - correct answer contains a string of letters
Variable - correct answer name that refers to a value
Assignment statement - correct answer gives value to a variable
Keyword - correct answer define the language's syntax rules and structure, and they
cannot be used as variable names
Statement - correct answer instruction that the Python interpreter can execute
Operators - correct answer special tokens that represent computations like addition,
multiplication and division
, Modulus operator - correct answer %, works on integers (and integer expressions) and
gives the remainder when the first number is divided by the second
Evaluate - correct answer To simplify an expression by performing the operations in
order to yield a single value.
Int - correct answer A Python data type that holds positive and negative whole numbers
Float - correct answer 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 answer The order in which statements are executed during a
program run.
Function - correct answer 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 answer A function that returns a value when it is called.
Local variable - correct answer 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 answer A name used inside a function to refer to the value which
was passed to it as an argument.
Boolean function - correct answer A function that returns a Boolean value. The only
possible values of the bool type are False and True.
None - correct answer 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 answer A group of consecutive statements with the same indentation.
Boolean expression - correct answer An expression that is either true or false.
Conditional statement - correct answer 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 answer One program structure within another, such as a
conditional statement inside a branch of another conditional statement
