python使用xlrd實現檢索excel中某列含有指定字串記錄的方法

本文執行個體講述了python使用xlrd實現檢索excel中某列含有指定字串記錄的方法。分享給大家供大家參考。具體分析如下：

這裡利用xlrd，將excel中某列資料中，含有指定字串的記錄取出，並產生用這個字串命名的txt檔案

import osimport xlrd,sys# input the excel fileFilename=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 filebk=xlrd.open_workbook(Filename)#get the sheets numbershxrange=range(bk.nsheets)print shxrange#get the sheets namefor x in shxrange:  p=bk.sheets()[x].name.encode('utf-8')  print "Sheets Number(%s): %s" %(x,p.decode('utf-8'))# input your sheets namesname=int(raw_input('choose the sheet number:'))try:  sh=bk.sheets()[sname]except:  print "no this sheet"  #return Nonenrows=sh.nrowsncols=sh.ncols# return the lines and col numberprint "line:%d col:%d" %(nrows,ncols)#input the check columncolumnnum=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 columntestin=raw_input('input the string:')#find the cols and save to a txtoutputfilename=testin + '.txt'outputfile=open(outputfilename,'w')#find the rows which you want to select and write to a txt filefor 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()

希望本文所述對大家的Python程式設計有所協助。
