Question

我写了下面的代码，并且不断出错。谁能帮我发现错误？函数roundGrade是我在代码上方拥有的一个函数，并且工作正常。

我想找到数字的平均值（最终等级），但有一些条件。有N个学生，他们已经分配了M个作业。如果M = 1，则最终成绩应为该作业的成绩。如果M> 1，则应除去最低等级，最终等级应为等级的平均值。如果其中一个等级为-3，则最终等级应为-3。这三个条件应该适用于我的代码。

def computeFinalGrades(grades):
    g = grades
    g2 = np.zeros(np.size(g[:,1]))

    for i in range(np.size(g2)):
        g3 = roundGrade(g[i,:])

        if np.any(g3) == -3:
            grade = -3
        elif np.size(g3) == 1:
            grade = g[0]
        elif np.size(g3) > 1:
            g4 = heapq.nlargest(np.size(g-1),g3)
            grade = roundGrade(np.mean(g4))
        else:
            print("Invalid input, please try again")
            g2[i] = grade

        gradesFinal = g2
        return gradesFinal

x = np.array([[1,2,-3,6],[2,3,9,0],[-3,4,8,7]])
print(computeFinalGrades(x))
