Introduction to Python - Lesson 5 Vocabulary

Flashcards covering key vocabulary terms from the Python programming lesson, focusing on loops, validation, and randomness.

Iteration

The computing term for repeating something again and again.

While-loop

A Python construct that keeps repeating a block of code while a certain condition is true.

Validation

Checking that inputted data is in the correct format, typically performed by a computer program.

Presence Checking

A type of validation that ensures something has been entered.

Existence Checking

A type of validation that ensures that data exists on a database.

Length Checking

A type of validation that ensures data is not too short or too long.

Format Checking

A type of validation that ensures data is in the correct form.

Verification

Showing a user what they have already inputted so they can check its correctness; usually performed by a person.

Pseudo-random Numbers (PRNs)

Numbers generated by algorithms that appear random but are produced using mathematical formulas or pre-calculated tables.

Random.seed()

Helps to make the numbers ‘more random’.

Random.randrange()

Picks a random number between two values.
