#02 Finally successfully resolved xls xlsx conversion, xls xlsx file copy, skip the same name

import os
import win32com.client as win32
import shutil


#####第一步先降原文件夹中的xlsx文件直接拷贝至bak文件夹中

file = []

path = os.getcwd()           #转换前程序所在文件目录

path_bak = os.getcwd() + r'/bak/'

pathdir = os.listdir(path)
for s in pathdir:
    newdir = os.path.join(path,s)
    if os.path.isfile(newdir):
        os.chdir(path_bak)
        pathdir_bak = os.listdir(path_bak)
        print(pathdir_bak)
        if os.path.splitext(newdir)[1] == ".xls" :
            t = os.path.split(s)[1] + r'x'
            if os.path.exists(t):
                print(os.path.exists(os.path.split(s)[1]))
                break
            else:
                excel = win32.gencache.EnsureDispatch('Excel.Application')
                wb = excel.Workbooks.Open(newdir)
                print(newdir)
                path_dir = os.path.split(newdir)[0]
                path_file = os.path.split(newdir)[1]
                print(path_dir)
                print(path_file)
                wb.SaveAs(path_dir  + '/bak/' + path_file + 'x', FileFormat=51)  # FileFormat = 51 is for .xlsx extension
                wb.Close()  # FileFormat = 56 is for .xls extension
                excel.Application.Quit()
        elif os.path.splitext(newdir)[1] == ".xlsx" :
            file.append(newdir)


    elif os.path.isdir(newdir):
        continue

for i in range(len(file)):
    pcm_file = file[i]
    path_0   = os.path.split(file[i])[0]
    path_1   = os.path.split(file[i])[1]
    oldname = path_0 + '/' + path_1
    newname = path_0 + r'/bak/' + path_1
    shutil.copyfile(oldname,newname)



#####第二步将文件目录切换至bak文件夹中，
os.chdir(path_bak)
pathdir_bak = os.listdir(path_bak)
#print(pathdir_bak)












'''
############转换前的文件夹
filelist_trans = []
path_trans = os.getcwd()           #转换前程序所在文件目录
print(path_trans)
pathlist_trans = os.listdir(path_trans)
print(pathlist_trans)

path_same_rear = 'bak'
path_same = path_trans + '/' + path_same_rear

############需要同步的文件夹
filelist_same = []
path_same_head = os.getcwd()
path_same_rear = 'bak'
path_same = path_same_head + '/' + path_same_rear
print(path_same)
os.chdir(path_same)
pathlist_same = os.listdir(path_same)




for trans in pathlist_trans:
    filelist_trans = os.path.join(path_trans, trans)  # 将文件名加入到当前文件路径后面
    print(filelist_trans)
    if os.path.isfile(filelist_trans):
        if os.path.splitext(filelist_trans)[1] == ".xlsx":
            print(os.path.splitext(filelist_trans))

           # shutil.copyfile(os.path.splitext(filelist_trans), path_same)





       # if os.path.splitext(filelist_trans)[1] == ".xls" and :  # 如果文件是".xls"后缀的



filelist_same = []

path_same_head = os.getcwd()
path_same_rear = 'bak'

path_same = path_same_head + '/' + path_same_rear


os.chdir(path_same)

myfile = '2.xlsx'


if os.path.exists(myfile):
    print(myfile)
'''
