Python代码：统计学生成绩及格人数和平均分

n = int(input('总人数:')) scores = [] for i in range(n): score = int(input('请输入第{}个学生的成绩:'.format(i+1))) scores.append(score)

pass_num = 0 pass_sum = 0 for score in scores: if score >= 60: pass_num += 1 pass_sum += score

if pass_num == 0: print('没有及格的学生') else: pass_avg = pass_sum / pass_num print('及格人数{}人，平均成绩是{:.2f}'.format(pass_num, pass_avg))
