1.xlrd主要是用来读取excel文件
import xlrd data = xlrd.open_workbook('abcd.xls') # 打开xls文件 table = data.sheets()[0] # 打开第一张表 nrows = table.nrows # 获取表的行数 for i in range(nrows): # 循环逐行打印 if i == 0:# 跳过第一行 continue print (table.row_values(i)[:13]) # 取前十三列
示例2:
#coding=utf-8 ####################################################### #filename:test_xlrd.py #author:defias #date:xxxx-xx-xx #function:读excel文件中的数据 ####################################################### import xlrd #打开一个workbook workbook = xlrd.open_workbook('E:CodePython estdata.xls') #抓取所有sheet页的名称 worksheets = workbook.sheet_names() print('worksheets is %s' %worksheets) #定位到sheet1 worksheet1 = workbook.sheet_by_name(u'Sheet1') """ #通过索引顺序获取 worksheet1 = workbook.sheets()[0] #或 worksheet1 = workbook.sheet_by_index(0) """ """ #遍历所有sheet对象 for worksheet_name in worksheets: worksheet = workbook.sheet_by_name(worksheet_name) """ #遍历sheet1中所有行row num_rows = worksheet1.nrows for curr_row in range(num_rows): row = worksheet1.row_values(curr_row) print('row%s is %s' %(curr_row,row)) #遍历sheet1中所有列col num_cols = worksheet1.ncols for curr_col in range(num_cols): col = worksheet1.col_values(curr_col) print('col%s is %s' %(curr_col,col)) #遍历sheet1中所有单元格cell for rown in range(num_rows): for coln in range(num_cols): cell = worksheet1.cell_value(rown,coln) print cell """ #其他写法: cell = worksheet1.cell(rown,coln).value print cell #或 cell = worksheet1.row(rown)[coln].value print cell #或 cell = worksheet1.col(coln)[rown].value print cell #获取单元格中值的类型,类型 0 empty,1 string, 2 number, 3 date, 4 boolean, 5 error cell_type = worksheet1.cell_type(rown,coln) print cell_type """

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文件的目的
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"新歌检索失败1477881109469_new.xlsx") wb = Workbook() ws = wb.active ws['A1'] = 4 wb.save("新歌检索失败.xlsx")
示例2:
import openpyxl # 新建文件 workbook = openpyxl.Workbook() # 写入文件 sheet = workbook.activesheet['A1']='A1' # 保存文件 workbook.save('test.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'H5应用中心关键数据及趋势.xlsx') worksheet = workbook.add_worksheet(u"每日PV,UV") headings = ['日期', '平均值'] 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': '每日页面分享数据'}) worksheet.insert_chart('H7', chart) workbook.close()
示例2:
import xlsxwriter as xw #新建excel workbook = xw.Workbook('myexcel.xlsx') #新建工作薄 worksheet = workbook.add_worksheet() #写入数据 worksheet.wirte('A1',1) #关闭保存 workbook.close()
合并表格实例:
#coding:utf-8 import xlsxwriter import xlrd #新建excel workbook = xlsxwriter.Workbook('广东.xlsx') #新建工作薄 worksheet = workbook.add_worksheet() count = 1 worksheet.write("A%s"%count,"公司名称") worksheet.write("B%s"%count,"法人") worksheet.write("C%s"%count,"电话") worksheet.write("D%s"%count,"注册资金") worksheet.write("E%s"%count,"注册时间") count+=1 for i in range(1,153): data = xlrd.open_workbook('ah (%s).xls'%i) # 打开xls文件 table = data.sheets()[0] # 打开第一张表 nrows = table.nrows # 获取表的行数 for i in range(nrows): # 循环逐行打印 if i == 0:# 跳过第一行 continue # print (table.row_values(i)[:5]) # 取前十三列 print(count,table.row_values(i)[:5][0]) #写入数据 #设定第一列(A)宽度为20像素 A:E表示从A到E worksheet.set_column('A:A',30) worksheet.set_column('B:E',20) worksheet.write("A%s"%count,table.row_values(i)[:5][0]) worksheet.write("B%s"%count,table.row_values(i)[:5][1]) worksheet.write("C%s"%count,table.row_values(i)[:5][2]) worksheet.write("D%s"%count,table.row_values(i)[:5][3]) worksheet.write("E%s"%count,table.row_values(i)[:5][4]) count+=1 #关闭保存 workbook.close()
