Extension: Change the sample values and test at least two different cases.
Find all measurements greater than 20.
Use a list comprehension with an if condition.
measures = [18, 21, 25, 13, 22]
above = [x for x in measures if x > 20]
print(above)

Extension: Change the sample values and test at least two different cases.
Remove duplicate names while retaining their first-seen order.
Append only when an item is not already in the result.
names = ["Ada", "Leo", "Ada", "Mia", "Leo"]
unique = []
for name in names:
if name not in unique:
unique.append(name)
print(unique)

Extension: Change the sample values and test at least two different cases.
Sort a list of temperatures from coldest to warmest.
sorted() returns a new list.
temperatures = [19, 12, 25, 18, 15]
print(sorted(temperatures))

Extension: Change the sample values and test at least two different cases.
Create cumulative totals from weekly savings.
Append a fresh running total after each amount.
savings = [3, 2, 5, 4]
running = []
total = 0
for amount in savings:
total += amount
running.append(total)
print(running)

Extension: Change the sample values and test at least two different cases.
Keep only the even numbers from a list.
Use n % 2 == 0.
values = [1, 4, 7, 12, 15, 20]
print([n for n in values if n % 2 == 0])

Extension: Change the sample values and test at least two different cases.
Combine names and scores into a series of readable results.
zip() pairs corresponding items.
names = ["Ada", "Ben", "Cara"]
scores = [9, 6, 8]
for name, score in zip(names, scores):
print(f"{name}: {score}")
