1、python操作excel需要用到的庫

python操作excel主要用到xlrd和xlwt這兩個庫，即xlrd是讀excel，xlwt是寫excel的庫。可以直接pip安裝這兩個庫，pip install xlrd 、pip install xlwt

2、python封裝常用讀取excel方法

# coding:utf-8
import xlrd
import sys

# 解決Unicode equal comparison failed to convert both arguments to Unicode - interpreting問題
# uncode編碼警告：在unicode等價比較中，把兩個引數同時轉換為unicode編碼失敗。中斷並認為他們不相等
 

# windows下的字串str預設編碼是ascii，而python編碼是utf8
reload(sys)
sys.setdefaultencoding('utf8')
