1.聲明一個(gè)字典保存一個(gè)學(xué)生的信息，學(xué)生信息中包括: 姓名、年齡、成績(jī)(單科)、電話(huà)

student = {'name': '明凱', 'age': 25, 'score': 77, 'tel': 1239424123}

2.聲明一個(gè)列表，在列表中保存6個(gè)學(xué)生的信息(6個(gè)題1中的字典)

student = [{'name': '明凱', 'age': 25, 'score': 77, 'tel': 1239424123},
           {'name': '林偉祥', 'age': 22, 'score': 71, 'tel': 1226424131},
           {'name': '曾甚然', 'age': 21, 'score': 55, 'tel': 1316445231},
           {'name': '童揚(yáng)', 'age': 19, 'score': 58, 'tel': 1426424131},
           {'name': '梁志斌', 'age': 24, 'score': 88, 'tel': 12227524131},
           {'name': '李元浩', 'age': 22, 'score': 73, 'tel': 12264224231}]

a.統(tǒng)計(jì)不及格學(xué)生的個(gè)數(shù)

num = 0
for x in student:
    if x.get('score') < 60:
        num += 1
print(num)

b.打印不及格學(xué)生的名字和對(duì)應(yīng)的成績(jī)

for x in student:
    if x.get('score') < 60:
        print(x.get('name'), x.get('score'))

c.統(tǒng)計(jì)未成年學(xué)生的個(gè)數(shù)

num = 0
for x in student:
    if x.get('age') < 18:
        num += 1
print(num)

d.打印手機(jī)尾號(hào)是8的學(xué)生的名字

for x in student:
    if x.get('tel')[-1] == '8':
        print(x.get('name'))

e.打印最高分和對(duì)應(yīng)的學(xué)生的名字

max_name = ''
max_score = 0
for x in student:
    if x['score'] > max_score:
        max_score = x['score']
        max_name = x['name']
print('高分:%d,名字:%s' % (max_score, max_name))

f.將列表按學(xué)生成績(jī)從大到小排序(掙扎一下，不行就放棄)
