Python——xlrd，xlwt读写Excel

Python对Excel的读写主要有xlrd、xlwt、xlutils、openpyxl、xlsxwriter几种。

1. xlrd主要是用来读取excel文件

import xlrd

workbook = xlrd.open_workbook(u'有趣装逼每日数据及趋势.xls')
sheet_names= workbook.sheet_names()
for sheet_name in sheet_names:
　　 sheet2 = workbook.sheet_by_name(sheet_name)
　　 print sheet_name rows = sheet2.row_values(3) # 获取第四行内容
　　 cols = sheet2.col_values(1) # 获取第二列内容
　　 print rows
　　 print cols

2. xlwt主要是用来写excel文件

import xlwt

wbk = xlwt.Workbook()
sheet = wbk.add_sheet('sheet 1')
sheet.write(0,1,'test text')#第0行第一列写入内容
wbk.save('test.xls')

3. xlutils结合xlrd可以达到修改excel文件目的

import xlrd
from xlutils.copy import copy

workbook = xlrd.open_workbook(u'有趣装逼每日数据及趋势.xls')
workbooknew = copy(workbook)
ws = workbooknew.get_sheet(0)
ws.write(3, 0, 'changed!')
workbooknew.save(u'有趣装逼每日数据及趋势copy.xls')

4.openpyxl可以对excel文件进行读写操作

from openpyxl import Workbook
from openpyxl import load_workbook
from openpyxl.writer.excel import ExcelWriter 

workbook_ = load_workbook(u"新歌检索失败1477881109469.xlsx")
sheetnames =workbook_.get_sheet_names() #获得表单名字
print sheetnames
sheet = workbook_.get_sheet_by_name(sheetnames[0])
print sheet.cell(row=3,column=3).value
sheet['A1'] = '47' 
workbook_.save(u"新文件_new.xlsx")  
wb = Workbook()
ws = wb.active
ws['A1'] = 4
wb.save("新文件.xlsx") 

5.xlsxwriter可以写excel文件并加上图表

import xlsxwriter
 
def get_chart(series):
    chart = workbook.add_chart({'type': 'line'})
    for ses in series:
        name = ses["name"]
        values = ses["values"]
        chart.add_series({ 
            'name': name,
            'categories': 'A2:A10',
            'values':values
        })  
    chart.set_size({'width': 700, 'height': 350}) 
    return chart
 
if __name__ == '__main__':
    workbook = xlsxwriter.Workbook(u'新文件1.xlsx') 
    worksheet = workbook.add_worksheet(u"测试")
    headings = ['日期', 'test']
    worksheet.write_row('A1', headings)
    index=0
    for row in range(1,10):
        for com in [0,1]:
            worksheet.write(row,com,index)
            index+=1  
    series = [{"name":"平均值","values":"B2:B10"}]
    chart = get_chart(series)
    chart.set_title ({'name': '测试数据1'})  
    worksheet.insert_chart('H7', chart)
    workbook.close()
