关于Numpy的一些简单问题解答，创建Numpy数组，计算班级分数

以下是关于分数计算的一段代码

# code
with open ('score.txt','r',encoding='utf-8') as f:
    content = [i[:-1].split(',') for i in f.readlines()]
print(content)
name = np.array(content).reshape(5,4)
name = name[:,0]
# print(name)

noname = content
for i in range(len(noname)):
    del noname[i][0]
# print(noname)

npcontent = np.array(noname).reshape(5,3)
# print(npcontent)
npcontent = np.array(npcontent,dtype=np.int64)
print('np格式的数据是n',npcontent)

npscore = npcontent.cumsum(1)
npscore = npscore[:,-1]
# print(npscore)

mean = 0
number = 0
steps = np.where(npscore>300,1,0)
for i in range(len(noname)):
    if steps[i] == 1:
        mean = (npscore[i])/3
        print(name[i],'的平均分是',mean)
    else:
        number = number+1

print('总分小于300分同学的人数是',number)
