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()
