Sedikit share kebodohanku, atau kejeniusanku, atau apalah, saat diriku mengerjakan mid di kelas. Kebetulan ada ujian mid yang openbook dan kami diperbolehkan buka laptop pula. Dan karena tidak ada kalkulator maka Python pun bisa kugunakan untuk perhitungan, berikut adalah kopas dari command prompt saat aku ujian hari ini dan kemarin:
