Tantangan

Mudah

Buat fungsi bernama filter_top_students yang menerima satu argumen: threshold (float). Fungsi ini harus:

Menelusuri dictionary student_records dan menemukan semua siswa yang nilai rata-ratanya lebih besar dari threshold yang ditentukan.
Menggunakan fungsi calculate_average_grade untuk mendapatkan nilai rata-rata setiap siswa.
Mengembalikan list nama siswa dengan nilai tertinggi.
Jika tidak ada siswa yang memenuhi kriteria, kembalikan list kosong.

Tambahkan (ganti) blok kode berikut di bagian bawah kodemu:

add_student("Alice", 20, ["Math", "Physics"])
add_student("Bob", 22, ["Math", "Biology"])
add_student("Diana", 23, ["Chemistry", "Physics"])
add_grade("Alice", 90)
add_grade("Alice", 85)
add_grade("Bob", 75)
add_grade("Diana", 95)
print(filter_top_students(80))  # Should return ["Alice", "Diana"]
print(filter_top_students(90))  # Should return ["Diana"]
print(filter_top_students(100))  # Should return an empty list

Luangkan waktu sejenak untuk merenungkan bagaimana kamu telah menggabungkan dictionary, set, dan pengambilan keputusan untuk membuat program yang berfungsi sepenuhnya. Bagus sekali! 🚀
