#python 写入excel
from openpyxl import Workbook
wb = Workbook()
sheet = wb.active
sheet.title = 'New sheet'#定义sheet的标题，下面的sheet名字
sheet['C3'] = 'hello'#C列，第三行，写入hello
for i in range(10):
    sheet['A%d' %(i+1)].value = i+1#循环遍历0到9，然后i+1 就是1到10，这句话表示A1-A10，写入1-10
sheet['E1'].value = '=SUM(A:A)'#在E1写入A列所有数据的和
wb.save('保存一个新的excel.xlsx')#保存到一个新的excel
