Review Summary

Excellent work on this! Your solution correctly implements the count_occurrences function and passes all requirements, so I am approving it. You did a great job handling the case-insensitivity requirement by converting both inputs to lowercase.

For future reference, you can make your code a bit more concise. Instead of converting the string to a list, you can call the .count() method directly on the string itself. This would allow you to simplify your function into a single line: return phrase.lower().count(letter.lower()).

Also, a small tip on coding conventions: using English for variable names is standard practice and makes code easier for a wider audience to read. These are just suggestions for improvement—your code works perfectly. Keep up the great work!

While this solution works perfectly, the conversion of the phrase to a list is an unnecessary intermediate step. Python's string objects have their own count() method, which you can use directly on the lowercased string. You could combine lines 2, 3, and 4 into a single return statement for a more concise solution.

Fixed in 5a3a660. Added ge=0 on offset and ge=1, le=5000 on limit via Field() constraints.
