python导出xlsx文件_python合并文件夹下的文件?

在电商行业中，每天都要去导流量来源信息进行商品数据分析，并需要对多天的数据进行粘贴复制，合并成一个数据表。多个表复制意味着重复的工作，基于此，怎样使用脚本对多个表进行合并，提高工作的效率呢？

路径拼接，形成完整的路径列表读取数据保存数据 路径拼接

找出在特定的目录下都有哪些需要合并的子表，返回完整路径列表

def IsSubString(SubStrList, Str):
    '''''
    #判断字符串Str是否包含序列SubStrList中的每一个子字符串
    #>>>SubStrList=['F','EMS','txt']
    #>>>Str='F06925EMS91.txt'
    #>>>IsSubString(SubStrList,Str)#return True (or False)
    '''
    flag = True
    for substr in SubStrList:
        if not (substr in Str):
            flag = False
    return flag


def fn_get_filelist(FindPath, FlagStr=[]):
    '''''
    #获取目录中指定的文件名
    #>>>FlagStr=['F','EMS','txt'] #要求文件名称中包含这些字符
    #>>>FileList=GetFileList(FindPath,FlagStr) #
    '''
    import os
    FileList = []
    FileNames = os.listdir(FindPath)
    if len(FileNames) > 0:
        for fn in FileNames:
            if len(FlagStr) > 0:
                # 返回指定类型的文件名
                if IsSubString(FlagStr, fn):
                    fullfilename = os.path.join(FindPath, fn)
                    FileList.append(fullfilename)
            else:
                # 默认直接返回所有文件名
                fullfilename = os.path.join(FindPath, fn)
                FileList.append(fullfilename)
                # 对文件名排序
    if (len(FileList) > 0):
        FileList.sort()
    for i in range(len(FileList)):
        print(FileList[i])

    return FileList

def read_excel(file_name):
    work = xlrd.open_workbook(file_name)
    sheet = work.sheet_by_index(0)
    rows = sheet.nrows

    rows_list = []
    for i in range(1, rows):
        rows_list.append(sheet.row_values(i))
    return rows_list

如上实现了xlrd读取数据，从第一行开始读取，排除表明。

def gather_excel(fn):
    workbook = xlwt.Workbook(encoding='utf-8')
    ws = workbook.add_sheet("流量来源详情")

    title_data = ["来源名称", "访客数", "浏览量", "支付金额", "浏览量占比", "店内跳转人数", "跳出本店人数", "收藏人数", "加购人数", "下单买家数", "下单转换率", "支付件数",
                  "支付买家数", "支付转换率", "直接支付买家", "收藏商品-支付买家数", "粉丝支付买家数", "加购商品-支付买家数"]
    target_list = [title_data]

    for n in range(len(title_data)):
        ws.write(0, n, target_list[0][n])

    index = 1

    for i in range(len(fn)):

        data_list = read_excel(fn[i])
        length_data_list = len(data_list)

        for j in range(length_data_list):
            list_line = data_list[j]

            target_list.append(list_line)
            for n in range(len(list_line)):
                ws.write(index, n, target_list[index][n])
            list_line.clear()
            index = index + 1
    save_result(workbook)

如果对于合并数据有所不接可以看我以前的文章，有详细的介绍，Python实现数据的读取和存储。

def save_result(wb):
    wb.save(target_file)
    print("存储成功！！！")

# This is a sample Python script.
import xlrd, xlwt

target_file = "./target_result_v1.xls"

    #>>>IsSubString(SubStrList,Str)#return True (or False)
