day7_读excel内容，写到数据库里

# 需求分析：
# 1、读出stu.xls文件里的内容
# 2、判断，如果是1用已交作业表示，如果是空用未交作业表示
# 3、拼接sql
# 4、插入到数据库里的jxz_stu表里，四个字段为name,c1,c2,c3

    import pymysql 
    conn = pymysql.connect(host = ‘211.149.218.16‘,user = ‘jxz‘,password = ‘123456‘,db = ‘jxz‘,charset = ‘utf8‘)

    cur = conn.cursor()
    cur.execute(sql)
    res = cur.fetchall()
    cur.close()
    conn.close()
    return res

def is_send(a): # 判断是否交作业了
    if a:
        return ‘已交作业‘
    else:
        return ‘未交作业‘

    book = xlrd.open_workbook(filename) # 打开指定的excel表
    sheet = book.sheet_by_name(‘Sheet1‘) # 读取Sheet1页的内容

    # print(sheet.nrows) # 打印出excel表里sheet1页的行数

    # print(sheet.ncols) # 打印出excel表里sheet1页的列数

    # print(sheet.cell(1,1)) # 获取第1行，第1列的值，打印出text:‘沙河‘

    # print(sheet.cell(1,1).value) # 获取到沙河
    for i in range(sheet.nrows): # 按照行循环
        lines= sheet.row_values(i) # 每行的内容
        name = lines[0]
