import sqlite3
connect = sqlite3.connect('student.db')
cursor = connect.cursor()
try:
    sql = '''create table student(
        [id]        integer PRIMARY KEY,
        [name]        varchar(50),
        [sex]        varchar(2),
        [age]        int
        );
        '''
    cursor.execute(sql)
except Exception as e:
    print("表已创建")

# 插入数据
sql = '''insert into student (id,name,sex,age) VALUES (?,?,?,?)'''
data = (1,"张1","男","")
cursor.execute(sql,data)
data = (2,"张2","女","")
cursor.execute(sql,data)
data = (3,"张3","男","")
cursor.execute(sql,data)
data = (4,"张4","女","")
cursor.execute(sql,data)

# 查数据
for select in cursor.execute("select * from student"):
    print("名称：%s ,\t 年龄：%s " %(select[1],select[3]))

# 删除数据
cursor.execute("delete from student")

# 删除表
cursor.execute("drop table student")

connect.commit()
connect.close()
