    Add a variable playerX to the data struct in the following init function, and set it equal to 100.
    def init(data): data.playerColor = "blue" import sys def set_certificate(certificate_div_id, certificate): document[certificate_div_id].textContent = certificate def get_student_code(student_code_div_id): raw_student_code = document[student_code_div_id].textContent return window.patchCodeToCheckTimeout(raw_student_code, 'check_timeout();'); class captureIO: def __init__(self): self.captured = [] def get_output(self): out = "" for c in self.captured: out += str(c) return out def write(self, data): self.captured.append(data) def flush(self): pass class data(object): pass def make_certificate(student_code_div_id, certificate_div_id): try: student_code = get_student_code(student_code_div_id) certificate = [] capture = captureIO() sys.stdout = capture sys.stderr = capture d = data() exec(student_code) init(d) certificate.append((d.playerX, type(d.playerX))) set_certificate(certificate_div_id, str(certificate)) except: set_certificate(certificate_div_id, "error")
