CSC 170 Exam 1 Vocabulary Flashcards

Vocabulary flashcards covering IPO, variables, Python basics, operators, conditionals, functions, and grading concepts from the notes.

IPO

Stands for Input, Process, Output: a model of how data flows through a program (input data, process it, then output results).

Variable attributes

Three main attributes: name (identifier), type (data type), and value (current data stored).

SEP

Separator string inserted between printed values (default is a space). (Can be used in replacement for the default spacing in comma's)

END

String appended at the end of the print output (default is a newline).

Arithmetic Operator precedence

Rules for the order of operations; (),**, left to right *,%,//,/ then +, -

MOD

%, returns the remainder of division; e.g., 55 % 3 = 1.

Floor division

//, division that discards fractional part; e.g., 55 // 3 = 18.

Exponentiation

**, raises a number to a power; e.g., 2 ** 3 = 8.

Comment out

Line comments start with # and are ignored by the interpreter.

Conditional patterns (3 kinds)

Simple if, if-else, and if-elif-else chains.

Relational operator

Operators that compare values: <, <=, >, >=, ==, != (yield booleans).

Logical operator

and, or, not; combine boolean expressions.

Boolean expressions

Expressions that evaluate to True or False.

Function return vs arguments vs variables (correspondence)

When unpacking a function's return, the number of items returned should match the number of variables receiving them.

Must all functions take arguments?

No. Functions can have zero parameters.

Must all functions return values?

No. Some functions return nothing (None).

Naming parameters vs arguments

Parameter names can be the same as argument values; parameters are names in a function definition, arguments are values passed in a call. (Yes they can be named the same)

Statement about parameters vs arguments (true/false)

True: Parameters appear in a function definition and arguments appear in a function call.
