Problem Framing: from context to evidence
Problem Framing connects question and source data to a checked finding in Python for AI & Data Science.
1Question and source data
Define the purpose, intended user and Python constraints.
frames
2Problem Framing
Write the decision first and identify the minimum supporting data.
produces evidence for
3Checked finding
Compare the observed result with a normal case, boundary case and stated limitation.
Takeaway: Problem Framing is credible only when the result can be traced back to its purpose, inputs and constraints. Problem Framing is the decision layer between the starting context and evidence that the result is fit for purpose.
Module 2
NumPy: Analysis
Apply NumPy through cleaning, exploration, modelling.

Cleaning: from context to evidence
Cleaning connects question and source data to a checked finding in Python for AI & Data Science.
1Question and source data
Define the purpose, intended user and Matplotlib constraints.

2Cleaning
Profile first, state rules and retain an audit of changes.
produces evidence for
3Checked finding
Compare the observed result with a normal case, boundary case and stated limitation.
Review the evidence, adjust the method, and repeat.
Takeaway: Cleaning is credible only when the result can be traced back to its purpose, inputs and constraints. Cleaning is the decision layer between the starting context and evidence that the result is fit for purpose.

3Checked finding
Compare the observed result with a normal case, boundary case and stated limitation.
Takeaway: Validation is credible only when the result can be traced back to its purpose, inputs and constraints. Validation is the decision layer between the starting context and evidence that the result is fit for purpose.
Module 4

2Workflow
Organise scripts so every output can be rebuilt.
produces evidence for
3Checked finding
Compare the observed result with a normal case, boundary case and stated limitation.
Takeaway: Workflow is credible only when the result can be traced back to its purpose, inputs and constraints. Workflow is the decision layer between the starting context and evidence that the result is fit for purpose.
Course practical outcome
Produce a reviewable Python for AI & Data Science project using Python, NumPy, Pandas.
Expected output: A working Python for AI & Data Science artefact plus an evidence-based self-review.
Tools: A suitable Python environment, A plain-text decision log, Test data or realistic sample material
Production steps
Define the intended user, outcome and constraints.
Create the smallest complete result using Python.
Test one normal case, one boundary case and one failure response.
Revise the work from the evidence and preserve before-and-after results.
Prepare a concise handover containing method, limitations and next step.
Success criteria
The output matches the stated outcome.
Inputs and decisions are reproducible.
Boundary and failure evidence is included.
Limitations and responsibility considerations are explicit.
Self-review
Can another learner repeat the method?
Did I test a difficult case?
Did I avoid unsupported claims?
Is the next action proportionate to the remaining risk?
Next step: Choose one weakness found during review and improve it before extending the Python scope.
