#python读取excel
from openpyxl import load_workbook
wb = load_workbook(\'test.xlsx\')
print(wb.sheetnames)

from openpyxl import load_workbook
wb = load_workbook(\'test.xlsx\')
sheet = wb.get_sheet_by_name(\'Sheet1\')
print(sheet[\'A\'])#列表A的所有数据
>>>(<Cell \'Sheet1\'.A1>, <Cell \'Sheet1\'.A2>, <Cell \'Sheet1\'.A3>, <Cell \'Sheet1\'.A4>, <Cell \'Sheet1\'.A5>, <Cell \'Sheet1\'.A6>, <Cell \'Sheet1\'.A7>, <Cell \'Sheet1\'.A8>, <Cell \'Sheet1\'.A9>, <Cell \'Sheet1\'.A10>)

print(sheet[\'4\'])#列表第四行的所有内容

>>>(<Cell \'Sheet1\'.A4>, <Cell \'Sheet1\'.B4>, <Cell \'Sheet1\'.C4>, <Cell \'Sheet1\'.D4>, <Cell \'Sheet1\'.E4>)

print(sheet[\'C4\'].value)
>>>哎哟哇

for i in sheet[\'C\']:
    print(i.value)

>>>c1
   c2
   c3
   哎哟哇
   c5
   c6

#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
