Python Validation and Verification

Teach validation and verification through a structured sequence of ten Python activities. Students begin with simple presence, range and length checks before progressing to type checks, format checks, check digits, visual verification and double entry. The course ends with a creative booking form where students combine several techniques in one program.

Each activity includes differentiated 1 chilli, 2 chillies and 3 chillies challenges so students can build confidence before adapting the code more independently. The teacher PowerPoint includes clear explanations, classroom notes, readable line-numbered code and worked solutions. Separate Python answer files make it quick to demonstrate or check each challenge.

The support materials include one card for each validation and verification technique, plus a separate decision flowchart to help students choose the correct check for a given situation.
