DayDayUP_Python自學記錄[15]_python execl 讀寫進階

讀取execl文件內容，txt to execl

導入模塊

  import xlrd

打開Excel文件讀取數據

   data = xlrd.open_workbook('excelFile.xls')

獲取一個工作表

獲取所有工作表的所有名稱

worksheets = data.sheet_names()

獲取所有工作表的總數目

sheetNum=len(data.sheets())

通過索引順序獲取1

table = data.sheets()[0] 

通過索引順序獲取2

table = data.sheet_by_index(0)

通過名稱獲取

table = data.sheet_by_name(u'Sheet1')

獲取整行和整列的值（數組）

table.row_values(i)
table.col_values(i)

獲取行數和列數

nrows = table.nrows
ncols = table.ncols

循環行列表數據

for i in range(nrows ):
    print table.row_values(i)

單元格數據

cell_A1 = table.cell(0,0).value

cell_C4 = table.cell(2,3).value

使用行列索引

cell_A1 = table.row(0)[0].value

cell_A2 = table.col(1)[0].value

txt2excel (複習上次的execl 寫入)

來源： 開源項目 show me the code

將txt文件寫入到execl中(包括花括號{}，方括號[] )

{
    "1":["wang",150,120,100],
    "2":["趙四",90,99,95],
    "3":["heh",60,66,68]
}

dict = json.loads(f.read().decode("GBK"))
xls = xlwt.Workbook() 
sheet = xls.add_sheet("student")
for i in range(len(dict.keys())):
    row = i
    col = 0
    sheet.write(row, col, dict.keys()[i])
    for j in (dict[dict.keys()[i]]):
        col+=1
        sheet.write(row, col, j )
xls.save(os.path.split(os.path.realpath(__file__))[0]+"/student.xls")

out：

2   李四  90  99  95

將txt文件寫入到execl中(包括花括號{}，不包含方括號[])
