💡 Hint

Common Mistakes

Using word instead of len(word) for length.

Using < instead of > for filtering.

We want the length of each word, so len(word). We filter words longer than 3, so > 3.

💡 Hint

Common Mistakes

Using k instead of k.upper() for keys.

Using < instead of > for filtering values.

Keys are converted to uppercase with k.upper(), values are v, and we filter values > 0.
