练习

请编写函数，在Sqlite中根据分数段查找指定的名字：

# -- coding: utf-8 --



import os, sqlite3



dbfile = os.path.join(os.path.dirname(_file), 'test.db')

if os.path.isfile(db_file):

os.remove(db_file)



# 初始数据:

conn = sqlite3.connect(db_file)

cursor = conn.cursor()

cursor.execute('create table user(id varchar(20) primary key, name varchar(20), score int)')

cursor.execute(r"insert into user values ('A-001', 'Adam', 95)")

cursor.execute(r"insert into user values ('A-002', 'Bart', 62)")

cursor.execute(r"insert into user values ('A-003', 'Lisa', 78)")

cursor.close()

conn.commit()

conn.close()



def get_score_in(low, high):

' 返回指定分数区间的名字，按分数从低到高排序 '



pass



# 测试:

assert get_score_in(80, 95) == ['Adam'], get_score_in(80, 95)

assert get_score_in(60, 80) == ['Bart', 'Lisa'], get_score_in(60, 80)

assert get_score_in(60, 100) == ['Bart', 'Lisa', 'Adam'], get_score_in(60, 100)



print('Pass')
