Check every reading
In "Alert level" you turned one engine temperature into OK, WARN or CRITICAL. Real telemetry doesn't arrive one number at a time: after each pass the ground station gets a whole list of readings, and every one of them needs the same check.
Run the check over the whole list, then add a summary the flight director can read at a glance.
Finish stage 1 to unlock this stage.
The check from "Alert level" handles one temperature. Make it check every temperature in temperatures_c and print each one with its level:
398.0 °C: OK 412.5 °C: WARN 455.2 °C: CRITICAL 401.7 °C: WARN 450.0 °C: CRITICAL 399.9 °C: OK
Replace the line temperature_c = 412.5 with for temperature_c in temperatures_c:, then indent the whole check and the print under it, so they run once for each temperature.
Finish stage 1 to unlock this stage.
After the list, print a summary: how many readings there were, and how many were WARN and CRITICAL:
398.0 °C: OK 412.5 °C: WARN 455.2 °C: CRITICAL 401.7 °C: WARN 450.0 °C: CRITICAL 399.9 °C: OK Readings: 6, WARN: 2, CRITICAL: 2
Set warn_count = 0 and critical_count = 0 before the loop, add 1 to the right one inside the WARN and CRITICAL branches, and print the summary after the loop, at the left edge.
Hints
For Loop Basics
# A for loop visits every item in a collection, one at a time
cargo = ["water", "food", "spare parts", "experiments"]
for item in cargo:
print("Loading:", item)
print("Hold sealed")
# The loop body can do real work, not just print
masses_kg = [820, 640, 310, 175]
total = 0
for mass in masses_kg:
total = total + mass
print("Total cargo:", total, "kg")
# A tuple of pairs unpacks straight into two variables
manifest = (("water", 820), ("food", 640), ("experiments", 175))
for name, mass in manifest:
print(f"{name}: {mass} kg")
# A string is a collection too, one character at a time
for letter in "CYGNUS":
print(letter, end=" ")
print()
# A set works as well, but the order is never promised
for module in {"Unity", "Harmony", "Destiny"}:
print("Docking check:", module)
