The task: write the report

Read trial.csv and print the report, in this order and these exact forms: - sessions: <n> - students: <n> - total minutes: <n> - one line per student, student <n>: <minutes> min, <cm> cm, numbered in the order they first appear - energy: <kwh> kWh rounded to 2 decimal places - cost: £<n> rounded to 2 decimal places - carbon: <n> g CO2 rounded to the nearest whole number - personal data in this report: none

# the two lines every program starts with: the commands, then the robot

The simulator checks it and tells you when it passes. Nothing to install, no account.

Challenges

  1. Add the average minutes per session, without naming anyone.
  2. Add a line comparing the carbon with something familiar, such as a car journey.
  3. Write three sentences of verdict for the school: two impacts and a recommendation.
