请耐心等待。我刚开始使用python才一周。问题是：我想连接到FTP服务器。假设我的ftp和本地目录上的文件结构是相同的。我想让我的python程序做以下事情：
1> 在运行程序时，它应该上传所有不在服务器上但在我的local（只上传丢失的文件，不替换所有文件）。比如说，我添加了一个新目录或一个新文件，它应该按原样上传到服务器上。2> 然后，它应该检查本地和服务器上文件的修改时间，并通知哪一个是最新的。
不，我做了两个程序：
1> 一个程序，将所有文件从本地上传到服务器，因为它是。我宁愿它检查丢失的文件，然后只上传丢失的文件文件夹。否不能全部更换。2> 第二个程序将使用os.walk列出本地的所有文件，并在不创建正确目录结构的情况下上传服务器上的所有文件。所有内容都被复制到服务器的根目录。然后它还会检查修改的时间。
我现在正在ames中尝试将这两个模块合并为一个完美的模块，以实现我所希望的一切。任何能够真正查看这些代码并尝试将它们与我想做的事情结合起来的人，都将是完美的。抱歉这么痛苦！！
附言：我可能不是每件事都这么简单！！
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")
代码2：

print("ServerFile:"+ServerTime)
if serverTimestamp > localTimestamp:
print ("Old Version on The Client. You need to update your copy of the file")
fo.write(str(datetime.now())+": Old Version of the file "+file2+" on the Clientn")
return
else:
print ("The File on the Server is Outdated!!!New COpy Uploaded")
fo.write(str(datetime.now())+": The server has an outdated file: "+file2+". An email is being generatedn")
ftp.storbinary('STOR '+file2, open(file2, 'rb'))
def Connect(pathToFile):
for path, subdirs, files in os.walk(pathToFile):
for name in files:
j=os.path.join(path, name)
print(j)
Connect_FTP(j,pathToFile)
Connect（"C:\temp\NVIDIA\Test"）
也许这个脚本会有用。
