【練習讀寫excel文件】創建workbook和批量創建Sheet

第一步，創建workbook和sheet

from openpyxl import Workbook

wb=Workbook()
wb.create_sheet(index=1,title="sheet2")

wb.save('test1.xlsx')

創建成功，workbook 名稱=test1，有sheet 和sheet2兩張表

  第二步，批量創建多個sheet

from openpyxl import Workbook
from openpyxl import load_workbook

wb=load_workbook('test1.xlsx')

for i in range(3):
    wb.create_sheet(index=1,title="sheet"+str(i))

wb.save('test1.xlsx')

創建成功

  第二步*-刪除 index=1對比結果

 第三步，在第一個sheet寫入數據rom openpyxl import Workbookfrom openpyxl import load_workbook

from openpyxl import Workbook

from openpyxl import load_workbook

wb=load_workbook('test1.xlsx') sheets=wb.worksheets #獲取當前所有的sheet  ws=wb.active ws['A1']='class' ws['B1']='name' ws['c1'].value='score' # ws.cell(row=1,colum=1)='class' # ws.cell(1,2).value='name' # ws.cell(1,3).value='score' row1=['class1','SC001','TC001'] row2=['class2','SC002','TC002'] row3=['class3','SC003','TC003'] row4=['class4','SC004','TC004'] ws.append(row1) ws.append(row2) ws.append(row3) ws.append(row4) 
#循環寫法

#for i in range(1,6):

    #row=[]

    #row.append('class'+str(i))

    #row.append('SC'+str("%03d"%i))  #數字前補充00對齊，三位數

    #row.append('TC'+str("%03d"%i))

    #ws.append(row)

wb.save('test1.xlsx')  

運行結果

  第四步，根據固定名稱批量創建sheet 

當前的表格數據

 

from openpyxl import Workbook
from openpyxl import load_workbook

wb=load_workbook('test1.xlsx')
sheets=wb.worksheets #獲取當前所有的sheet

#獲取某列的值
col1=[]
for col in sheets[0]['B']:
    col1.append(col.value)
col2=col1[1:]  #去除第一行的字段
print(col2)

# 批量新增sheetB
for i in range(len(col2)):
    wb.create_sheet(title=col2[i])

wb.save('test1.xlsx')    

運行完成后的表格
