【练习读写excel文件】创建workbook和批量创建Sheet

第一步，创建workbook和sheet

from openpyxl import Workbook

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

wb.save('test1.xlsx')

创建成功，workbook 名称=test1，有sheet 和sheet2两张表

第二步，批量创建多个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')

创建成功

第二步*-删除 index=1对比结果

第三步，在第一个sheet写入数据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 #获取当前所有的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)

#循环写法

#for i in range(1,6):

#row=[]

#row.append('class'+str(i))

#row.append('SC'+str("%03d"%i)) #数字前补充00对齐，三位数

#row.append('TC'+str("%03d"%i))

#ws.append(row)

wb.save('test1.xlsx')

运行结果

第四步，根据固定名称批量创建sheet

当前的表格数据

from openpyxl import Workbook
from openpyxl import load_workbook

wb=load_workbook('test1.xlsx')
sheets=wb.worksheets #获取当前所有的sheet

#获取某列的值
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')
