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 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()
