import xlrd, xlwt, xlutils
############ 读excel ###############
book = xlrd.open_workbook('C:\UserslingyulDesktopstudents.xlsx')#打开excel
print(book.sheet_names())#获取所有sheet页的名字
sheet1 = book.sheet_by_index(0)##根据sheet页的下标获取sheet页
sheet2 = book.sheet_by_name('students')#根据sheet页的名字获取sheet页
print(sheet1,sheet2)
print('row_all',sheet1.nrows)#获取所有行数
print('ncols_all',sheet1.ncols)#获取所有列数
print(sheet1.row_values(0))#根据行号打印某一行
sheet1.row_values(0)[0]#第0行的第0个元素
print(sheet1.col_values(0))#根据列号打印某一列
sheet1.col_values(0)[0]#第0列的第0个元素
print('####',sheet1.cell(2,2).value)#不加value的运行结果为：text:'小明'。打印第二行第二列的数据，即获取单元格数据
lis=[]
sheet1 = book.sheet_by_index(0)
ncols_all = sheet1.ncols
for row in range(1,sheet1.nrows):
    students = {}
    id = sheet1.cell(row, 0).value
    name = sheet1.cell(row, 1).value
    sex = sheet1.cell(row, 2).value
    students['id']=id
    students['name']=name
    students['sex']=sex
    lis.append(students)
print(lis)

############ 写excel ###############
