python操作Excel的几种方式

Posted 2020-10-13 帅胡

  1 Python对Excel的读写主要有xlrd、xlwt、xlutils、openpyxl、xlsxwriter几种。
  2 
  3 1.xlrd主要是用来读取excel文件
  4 
  5 import xlrd
  6 
  7 workbook = xlrd.open_workbook(u‘有趣装逼每日数据及趋势.xls‘)
  8 
  9 sheet_names= workbook.sheet_names()
 10 
 11 for sheet_name in sheet_names:
 12 
 13 　　 sheet2 = workbook.sheet_by_name(sheet_name)
 14 
 15 　　 print sheet_name rows = sheet2.row_values(3) # 获取第四行内容
 16 
 17 　　 cols = sheet2.col_values(1) # 获取第二列内容
 18 
 19 　　 print rows
 20 
 21 　　 print cols
 22 
 23  
 24 
 25 2.xlwt主要是用来写excel文件
 26 
 27 import xlwt
 28 
 29 wbk = xlwt.Workbook()
 30 
 31 sheet = wbk.add_sheet(‘sheet 1‘)
 32 
 33 sheet.write(0,1,‘test text‘)#第0行第一列写入内容
 34 
 35 wbk.save(‘test.xls‘)
 36 
 37  
 38 
 39 3.xlutils结合xlrd可以达到修改excel文件目的
 40 
 41 import xlrd
 42 
 43 from xlutils.copy import copy
 44 
 45 workbook = xlrd.open_workbook(u‘有趣装逼每日数据及趋势.xls‘)
 46 
 47 workbooknew = copy(workbook)
 48 
 49 ws = workbooknew.get_sheet(0)
 50 
 51 ws.write(3, 0, ‘changed!‘)
 52 
 53 workbooknew.save(u‘有趣装逼每日数据及趋势copy.xls‘)
 54 
 55  
 56 
 57 4.openpyxl可以对excel文件进行读写操作
 58 
 59 from openpyxl import Workbook
 60 
 61 from openpyxl import load_workbook
 62 
 63 from openpyxl.writer.excel import ExcelWriter 
 64 
 65  
 66 
 67 workbook_ = load_workbook(u"新歌检索失败1477881109469.xlsx")
 68 
 69 sheetnames =workbook_.get_sheet_names() #获得表单名字
 70 
 71 print sheetnames
 72 
 73 sheet = workbook_.get_sheet_by_name(sheetnames[0])
 74 
 75 print sheet.cell(row=3,column=3).value
 76 
 77 sheet[‘A1‘] = ‘47‘ 
 78 
 79 workbook_.save(u"新歌检索失败1477881109469_new.xlsx")  
 80 
 81 wb = Workbook()
 82 
 83 ws = wb.active
 84 
 85 ws[‘A1‘] = 4
 86 
 87 wb.save("新歌检索失败.xlsx") 
 88 
 89      
 90 
 91 5.xlsxwriter可以写excel文件并加上图表
 92 
 93 import xlsxwriter
 94 
 95  
 96 
 97 def get_chart(series):
 98 
 99     chart = workbook.add_chart({‘type‘: ‘line‘})
100 
101     for ses in series:
102 
103         name = ses["name"]
104 
105         values = ses["values"]
106 
107         chart.add_series({ 
108 
109             ‘name‘: name,
110 
111             ‘categories‘: ‘A2:A10‘,
112 
113             ‘values‘:values
114 
115         })  
116 
117     chart.set_size({‘width‘: 700, ‘height‘: 350}) 
118 
119     return chart
120 
121  
122 
123 if __name__ == ‘__main__‘:
124 
125     workbook = xlsxwriter.Workbook(u‘H5应用中心关键数据及趋势.xlsx‘) 
126 
127     worksheet = workbook.add_worksheet(u"每日PV,UV")
128 
129     headings = [‘日期‘, ‘平均值‘]
130 
131     worksheet.write_row(‘A1‘, headings)
132 
133     index=0
134 
135     for row in range(1,10):
136 
137         for com in [0,1]:
138 
139             worksheet.write(row,com,index)
140 
141             index+=1  
142 
143     series = [{"name":"平均值","values":"B2:B10"}]
144 
145     chart = get_chart(series)
146 
147     chart.set_title ({‘name‘: ‘每日页面分享数据‘})  
148 
149     worksheet.insert_chart(‘H7‘, chart)
150 
151     workbook.close()
