本文实例讲述了python使用xlrd实现检索excel中某列含有指定字符串记录的方法。分享给大家供大家参考。具体分析如下：

这里利用xlrd，将excel中某列数据中，含有指定字符串的记录取出，并生成用这个字符串命名的txt文件

import os
import xlrd,sys
# input the excel file
Filename=raw_input(\'input the file name&path:\')
if not os.path.isfile(Filename):
  raise NameError,\"%s is not a valid filename\"%Filename
#open the excel file
bk=xlrd.open_workbook(Filename)
#get the sheets number
shxrange=range(bk.nsheets)
print shxrange
#get the sheets name
for x in shxrange:
  p=bk.sheets()[x].name.encode(\'utf-8\')
  print \"Sheets Number(%s): %s\" %(x,p.decode(\'utf-8\'))
# input your sheets name
sname=int(raw_input(\'choose the sheet number:\'))
try:
  sh=bk.sheets()[sname]
except:
  print \"no this sheet\"
  #return None
nrows=sh.nrows
ncols=sh.ncols
# return the lines and col number
print \"line:%d col:%d\" %(nrows,ncols)
#input the check column
columnnum=int(raw_input(\'which column you want to check pls input the num(the first colnumn num is 0):\'))
while columnnum+1>ncols:
  columnnum=int(raw_input(\'your num is out of range,pls input again:\'))
# input the searching string and column
testin=raw_input(\'input the string:\')
#find the cols and save to a txt
outputfilename=testin + \'.txt\'
outputfile=open(outputfilename,\'w\')
#find the rows which you want to select and write to a txt file
for i in range(nrows):
  cell_value=sh.cell_value(i, columnnum)
  if testin in str(cell_value):
    outputs=sh.row_values(i)
    for tim in outputs:
      outputfile.write(\'%s  \' %(tim))
    outputfile.write(\'%s\' %(os.linesep)) 
outputfile.close()

希望本文所述对大家的Python程序设计有所帮助。
