python 通过pandas操作excel

一、准备工作

解决lzma 告警问题（如果有）：

yum install xz-devel

yum install python-backports-lzma

pip install backports.lzma

cd /usr/local/python3/lib/python3.8 

vim lzma.py

第27行修改：

try: from _lzma import * from _lzma import _encode_filter_properties, _decode_filter_propertiesexcept ImportError: from backports.lzma import * from backports.lzma import _encode_filter_properties, _decode_filter_properties

二、

pip install pandas

import pandas as pd

  2

  3 #读取xlsx、xls数据

  4 df = pd.read_excel('fruit2.xlsx')

  5 print(df)

  6 print(df.values)

  7 print(df['名称'])

  8 print(df.loc[1])

  9 print(df.loc[2,'单价/元'])

10

11 df = df.set_index('名称')  #设置名称列为行索引

12 print(df)

13 print(df.values)

14 print(df['库存/kg'])

15 print(df.loc['苹果'])

16 print(df.loc['香蕉','单价/元'])

17 #写入xlsx、xls

18 writer = pd.ExcelWriter('pandas.xlsx')

19 df.to_excel(writer,'sheet1')

20 writer.save()
