💡 Hint

Common Mistakes

Using the word itself as the value instead of its length.

Using the wrong comparison operator in the condition.

The dictionary comprehension uses len(word) to get the length and filters words with length greater than 3 using >.

Common Mistakes

Not converting keys to uppercase.

Using wrong comparison operators or filtering conditions.

The keys are converted to uppercase with k.upper(), values are kept as v, and only items with values greater than 0 are included using >.
