Python处理Excel数据分组

描述：将Excel表中的数据按照每50个进行分组，并输出保存到不同的文件。

#coding=utf-8
import xlrd

def read(file):
    data = xlrd.open_workbook(file)
    table = data.sheets()[0]
    nrows = table.nrows
    ncols = table.ncols
    

    n = 0
    
    filename = 1
    fopen = open('d:/zemail/'+str(filename)+'.txt', 'w')

    for i in xrange(0, nrows):
        rowValues = table.row_values(i)
        n = n+1
        if n%51 != 0:
            for item in rowValues:
                #print item
                fopen.write(item+'
')
        else:
            fopen.close()
            filename = n
            fopen = open('d:/zemail/'+str(filename)+'.txt', 'w')
    fopen.close()
        

#def create(filename):
    #if os.path.exists(fname):
        #print "File already exists!"
    #fopen = open(filename, 'w')
    #fopen.close()
