Group these words by their length, in a dictionary where the key is the length and the value is the list of words: ["cat", "tree", "dog", "bird", "sun", "house"]. Show the groups from the shortest length to the longest.
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 key is len(word). The value is a list. If the key is new, make an empty list. Then append.
Check. The lengths are 3 for cat, dog and sun; 4 for tree and bird; 5 for house. The output is
text
3 ['cat', 'dog', 'sun']
4 ['tree', 'bird']
5 ['house']The keys are numbers here, which is fine: a number is a fixed value and can be a key.
Answer: The program above.
