A collection of program statements that is part of a program.

What is a Conditional Expression in python?

A comparison, usually in a while or if statement, that evaluates to a Boolean value of True or False

What is a decidable problem?

A decision problem for which an algorithm can be written to produce correct output for all inputs (e.g., "Is the number even?").

What is an undecidable problem?

A decision problem for which no algorithm can be constructed that is always capable of providing a correct yes-or-no answer.

What is an Iteration in python

A repeating portion of an algorithm. Iteration repeats a specified number of times or until a given condition is met. Also used to refer to a single execution of that repetitive procedure.

What is a Boolean in python?

What is a while loop in python?

Loops while condition is true

What are Relational Operators in python?
