Using word instead of len(word) for the value

We use len(word) to get length and filter words with length greater than 3 using >.

5fill in blank

hard

Fill all three blanks to create a filtered dictionary with uppercase keys and values greater than 0.

💡 Hint

Common Mistakes

Using k.lower() instead of k.upper()

Using < instead of > in the condition

Swapping keys and values

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