Combine code and explanation

Combine code and explanation — guided practice

Connect notebook outputs to a precise narrative and independent checks.

Use free local JupyterLab with a Python 3 kernel, or an equivalent notebook environment that can read uploaded local files. Put analysis.ipynb and attendance.csv in the same new practice folder; no extra Python packages are used by the analysis. The CSV rows are S1 north 8 held; S2 south 6 held; S3 north blank held; S4 south 0 canceled; S5 north 7 held; S6 south 5 held; S7 north 4 held; S8 south 9 held. The supplied analyze.py runs the same calculation with Python from this folder. Use only these fictional records.

1. 1. Inspect code and text cells

   Identify the Markdown question, executable cell and interpretation cell.

   You should see: Narrative and executable evidence occupy distinct cell types.

   Readers need both reasoning and a way to rerun it.

2. 2. Check site totals

   Read by_site in result.json and add the included rows by hand.

   You should see: north=8+7+4=19; south=6+5+9=20.

   An independent calculation checks grouping.

3. 3. Check reconciliation

   Read the two assertions and verify 6+2=8 and 19+20=39.

   You should see: Both accounting identities hold.

   Assertions test structural consistency, not every possible truth.

4. 4. Write the interpretation

   State 39 recorded visits across 6 included sessions; two rows excluded; north 19/south 20.

   You should see: The text matches the output and unit.

   Do not turn a count difference into a causal explanation.
