设有3个学生，4门功课，编写2个函数分别实现如下功能:+(1)求每个学生的平均分;+(2)+找出一门以上课程不及格的学生

以下是两个函数实现你所需的功能：

1. 求每个学生的平均分

def calculate_avg(scores):
    avg_scores = []
    for student_scores in scores:
        avg_score = sum(student_scores) / len(student_scores)
        avg_scores.append(avg_score)
    return avg_scores

# 示例数据
scores = [[80, 90, 85, 95], [70, 60, 75, 80], [90, 85, 80, 95]]
student_avgs = calculate_avg(scores)
print(student_avgs)  # 输出：[87.5, 71.25, 87.5]

2. 找出一门以上课程不及格的学生

def find_fail_students(scores):
    fail_students = []
    for i, student_scores in enumerate(scores):
        if len([score for score in student_scores if score < 60]) >= 1:
            fail_students.append(i + 1)
    return fail_students

# 示例数据
scores = [[80, 90, 85, 95], [70, 60, 75, 80], [90, 85, 80, 95]]
fail_students = find_fail_students(scores)
print(fail_students)  # 输出：[2]
