Write each loop as a list comprehension.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Plan. The shape is [expression for item in iterable if condition]. The expression is what is appended, and the condition is the if.
- The first loop appends
len(w)for every word:[len(w) for w in words]. - The second loop appends
w.upper()only whenlen(w) > 3:[w.upper() for w in words if len(w) > 3].
Check. The lengths are 3, 8, 3 and 5. The words longer than 3 letters are notebook and ruler, in capitals.
Answer: [3, 8, 3, 5] and ['NOTEBOOK', 'RULER'].
