制作一个良好的FTP检查Python程序有困难
请耐心听我说。我刚学了Python一周，遇到了一个问题：我想连接到一个FTP服务器。假设我的FTP服务器和本地文件夹的文件结构是一样的。我希望我的Python程序能做到以下几点：
1> 当我运行程序时，它应该上传所有在服务器上没有的文件，也就是只上传缺失的文件，而不是替换所有文件。比如，我添加了一个新文件夹或新文件，它应该直接上传到服务器上。
2> 然后，它应该检查本地文件和服务器文件的修改时间，并告诉我哪个是最新的。
现在，我已经写了两个程序：
1> 第一个程序会把本地的所有文件直接上传到服务器。我希望它能先检查缺失的文件，然后只上传那些缺失的文件夹，而不是替换所有文件。
2> 第二个程序会使用os.walk列出本地的所有文件，并把所有文件上传到服务器，但没有创建正确的文件夹结构。所有文件都被复制到服务器的根目录。然后它还会检查修改时间。
我现在很困惑，想把这两个程序合并成一个完美的程序，完成我想要的功能。如果有人能帮我看看这些代码，帮我把它们合并成我想要的样子，那就太好了。抱歉让大家烦恼了！
附注：我可能没有用最简单的方法来做这些事情！
代码1：
import sys
from ftplib import FTP
import os
def uploadDir(localdir,ftp):
"""
for each directory in an entire tree
upload simple files, recur into subdirectories
"""
localfiles = os.listdir(localdir)
for localname in localfiles:
localpath = os.path.join(localdir, localname)
print ('uploading', localpath, 'to', localname)
if not os.path.isdir(localpath):
os.chdir(localdir)
ftp.storbinary('STOR '+localname, open(localname, 'rb'))
else:
try:
ftp.mkd(localname)
print ('directory created')
except:
print ('directory not created')
ftp.cwd(localname) # change remote dir
uploadDir(localpath,ftp) # upload local subdir
ftp.cwd('..') # change back up
print ('directory exited')
def Connect(path):
ftp = FTP("127.0.0.1")
print ('Logging in.')
ftp.login('User', 'Pass')
uploadDir(path,ftp)
Connect("C:\\temp\\NVIDIA\\Test")
