1.声明一个字典保存一个学生的信息，学生信息中包括: 姓名、年龄、成绩(单科)、电话
student1 = {'name': '小华', 'age': 18, 'grade': '79','tel': '13222223435'}
2.声明一个列表，在列表中保存6个学生的信息(6个题1中的字典)
a.统计不及格学生的个数
b.打印不及格学生的名字和对应的成绩
c.统计未成年学生的个数
d.打印手机尾号是8的学生的名字
e.打印最高分和对应的学生的名字

student = [
            {'name': '喜洋洋', 'age': 16, 'grade': 100,'tel': 13222223438},
            {'name': '美洋洋', 'age': 15, 'grade': 95, 'tel': 13222223435},
            {'name': '沸羊羊', 'age': 17, 'grade': 86, 'tel': 13222223435},
            {'name': '懒洋洋', 'age': 14, 'grade': 43, 'tel': 13222223435},
            {'name': '红太狼', 'age': 24, 'grade': 53, 'tel': 13222223435},
            {'name': '灰太狼', 'age': 25, 'grade': 79, 'tel': 13222223435}
          ]
list1 = []

count = 0
count1 = 0
g_max = 0
youxiurencai = ''
for people in student:
    for grade in people:
        if people['grade'] < 60:
            print('不及格学生姓名：', people['name'],'成绩', people['grade'])
            count += 1
            break
    for age in people:
        if people['age'] < 18:
            count1 += 1
            break
    for tel in people:
        if people['tel'] % 10 == 8:
            print('手机尾号是8的学生：',people['name'])
            break
    for grade in people:
        if people['grade'] > g_max:
            g_max = people['grade']
    for name in people:
        if people['grade'] == g_max:
            youxiurencai = people['name']
print('不及格学生个数:', count, '未成年人数:', count1)
print('最高分：', g_max,'优秀人才：', youxiurencai)

f.将列表按学生成绩从大到小排序(挣扎一下，不行就放弃)

students = [
            {'name': '喜洋洋', 'age': 16, 'grade': 85, 'tel': 13222223438},
            {'name': '美洋洋', 'age': 15, 'grade': 95, 'tel': 13222223435},
            {'name': '沸羊羊', 'age': 17, 'grade': 86, 'tel': 13222223435},
            {'name': '懒洋洋', 'age': 14, 'grade': 43, 'tel': 13222223435},
            {'name': '红太狼', 'age': 24, 'grade': 53, 'tel': 13222223435},
            {'name': '灰太狼', 'age': 25, 'grade': 79, 'tel': 13222223435}
          ]

new_list = []
while True:
    garde1 = 0
    for student in students:
        if student['grade'] > garde1:
            garde1 = student['grade']
            dictx = student 
            
    new_list.append(dictx)
    students.remove(dictx)
    if students == []:
        break
     
print(new_list)
