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
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:
#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:\\\\Code\\\\Python\\\\testdata.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
#Python学习交流群:778463939
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:
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()
openpyxl
示例:
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()
