Section 1
(50 cards)
nested conditional
A conditional statement that appears in one of the branches of another conditional statement.
operator
A special symbol that represents a simple computation like addition, multiplication, or string concatenation.
return value
The result of a function. If a function call is used as an expression, the return value is the value of the expression.
conditional statement
A statement that controls the flow of execution depending on some condition. An "if" statement.
logical operator
One of the operators that combines boolean expressions: and, or, and not.
initialize
An assignment that gives an initial value to a variable that will be updated.
parse
To examine a program and analyze the syntactic structure.
accumulator
A variable used in a loop to add up or accumulate a result.
short circuit
When Python is part-way through evaluating a logical expression and stops the evaluation because Python knows the final value for the expression without needing to evaluate the rest of the expression.
concatenate
To join two operands end to end.
counter
A variable used in a loop to count the number of times something happened. We initialize a counter to zero and then increment the counter each time we want to "count" something.
expression
A combination of variables, operators, and values that represents a single result value.
pseudorandom
Pertaining to a sequence of numbers that appear to be random, but are generated by a deterministic program.
fruitful function
A function that returns a value.
type
A category of values. The types we have seen so far are integers (type int), floating-point numbers (type float), and strings (type str).
portability
A property of a program that can run on more than one kind of computer.
evaluate
To simplify an expression by performing the operations in order to yield a single value.
function call
A statement that executes a function. It consists of the function name followed by an argument list.
increment
An update that increases the value of a variable (often by one).
assignment
A statement that assigns a value to a variable. Uses a single "=" sign x = 5
semantics
The meaning of a program.
statement
A section of code that represents a command or action.
function definition
A statement that creates a new function, specifying its name, parameters, and the statements it executes.
semantic error
An error in a program that makes it do something other than what the programmer intended.
deterministic
Pertaining to a program that does the same thing each time it runs, given the same inputs.
parameter
A name used inside a function to refer to the value passed as an argument.
function
A named sequence of statements that performs some useful operation. Functions may or may not take arguments and may or may not produce a result.
body
The sequence of statements inside a function definition.
compound statement
A statement that consists of a header and a body. The header ends with a colon (:). The body is indented relative to the header. Example: if ________: ------------ ------------ else: --------------
composition
Using an expression as part of a larger expression, or a statement as part of a larger statement.
boolean expression
An expression whose value is either True or False. Usually contains a comparison operator: ==, !=, >, <, >=, <=, is, is not
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. - Uses "#" at beginning. Everything after the "#" is ignored. - Can be at the beginning of a line and take the whole line - Can be after a programming statement, explaining the statement
guardian pattern
Where we construct a logical expression with additional comparisons (like try/except) to take advantage of the short-circuit behavior (to keep from getting 0 in a denominator.
prompt
When a program displays a message and pauses for the user to type some input to the program.
dot notation
The syntax for calling a function in another module by specifying the module name followed by a dot (period) and the function name.
condition
The boolean expression in a conditional statement that determines which branch is executed.
function object
A value created by a function definition. The name of the function is a variable that refers to a function object.
header
The first line of a function definition.
modulus operator
An operator, denoted with a percent sign (%), that works on integers and yields the remainder when one number is divided by another.
import statement
A statement that reads a module file and creates a module object.
flow of execution
The order in which statements are executed during a program run.
argument
A value provided to a function when the function is called. This value is assigned to the corresponding parameter in the function, within the parentheses.
decrement
An update that decreases the value of a variable.
problem solving
The process of formulating a problem, finding a solution, and expressing the solution.
operand
One of the values on which an operator operates.
algorithm
A methodical step-by-step process for solving a category of problems.
comparison operator
One of the operators that compares its operands: ==, !=, >, <, >=, and <=.
traceback
A list of the functions that are executing, printed when an exception occurs.
void function
A function that does not return a value.
module object
A value created by an import statement that provides access to the data and code defined in a module.
