NumPy 成绩统计

1.随机数生成六个班的考试成绩，3门考试：Python、数学、语文。每个班50人

import numpy as np # 导入模块
grade1 = np.random.randint(0,100,size = (50,3))
grade2 = np.random.randint(0,100,size = (50,3))
grade3 = np.random.randint(0,100,size = (50,3))
grade4 = np.random.randint(0,100,size = (50,3))
grade5 = np.random.randint(0,100,size = (50,3))
grade6 = np.random.randint(0,100,size = (50,3))
grade1,grade2,grade3,grade4,grade5,grade6

2.将六个班的考试成绩进行合并得到score

score = np.concatenate([grade1,grade2,grade3,grade4,grade5,grade6])

3.生成性别数组sex，水平叠加数组sex和score得到data

sex = np.random.randint(0,2,size = (300,1))
data = np.hstack((s
