上代码：
from openpyxl import load_workbook
from datetime import datetime
def create_time():
now_year = datetime.now().year
wb = load_workbook('C:/Users/admin/Desktop/11.xlsx')
sh = wb.active
max_column = sh.max_column
for i,cell in enumerate(sh['B']):
pno = cell.value
# print(pno)
##身份证的特点： #6位行政划分 4位年 2位月 2位日 4位个人编码
year = pno[6:10]
month = pno[10:12]
day = pno[12:14]
print(f'year:{year} month:{month} day:{day}')
age = now_year - int(year)
sh.cell(i + 1,max_column + 1).value = year
sh.cell(i + 1, max_column + 2).value = month
sh.cell(i + 1, max_column + 3).value = day
sh.cell(i + 1, max_column + 4).value = age
wb.save('C:/Users/admin/Desktop/time.xlsx')
if __name__ == "__main__":
create_time()
实现效果；

坑：data表格中有空格导致，即有空值导致

使用11.xlsx数据就可以了
