Thai OMR answer sheet generator
Thai OMR answer sheet generator is a Python library that creates printable answer sheets for optical mark recognition (OMR) in Thai and English. He first wrote it so that a teacher could grade homework without checking every answer by hand, then rewrote and published it for others to use.
What it generates
- Answer sheets with the exam title, subject, date and student details, and a QR code identifying the student.
- Blank sheets for students to fill in themselves.
- True/false tests, essay sections and sections with their own scores.
- Answer keys.
- Batches of sheets, from a list in code or from a CSV file of students.
Choices come in presets: Thai letters (ก ข ค ง, with or without จ), Thai true/false (ถูก/ผิด), English letters or numbers. Custom labels such as α β γ δ also work.
How it's built
It draws the PDFs with ReportLab, makes the QR codes with the qrcode package and bundles a Thai font, so the sheets look the same on any machine. An example run takes a few lines:
generator = OMRGenerator()
exam = ExamConfig(exam_title="สอบปลายภาคเรียนที่ 2", subject_name="วิทยาศาสตร์ (ป.4)")The README's disclaimer is candid. The original code was messy, the published version was rewritten with an AI assistant, and some parts may still behave oddly.
