python使用xlrd实现检索excel中某列含有指定字符串记录的方法

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()
