1. os.system

   
     

    
      
    
      import
    
       os

    
      import
    
       tempfile

filename1 
    
      =
    
       tempfile.mktemp (
    
      "
    
      .txt
    
      "
    
      )
open (filename1, 
    
      "
    
      w
    
      "
    
      ).close ()
filename2 
    
      =
    
       filename1 
    
      +
    
       
    
      "
    
      .copy
    
      "
    
      

    
      print
    
       filename1, 
    
      "
    
      =>
    
      "
    
      , filename2


    
      #
    
      拷文件
    
      

    
      os.system (
    
      "
    
      copy %s %s
    
      "
    
       
    
      %
    
       (filename1, filename2))


    
      if
    
       os.path.isfile (filename2): 
    
      print
    
       
    
      "
    
      Success
    
      "
    
      

dirname1 
    
      =
    
       tempfile.mktemp (
    
      "
    
      .dir
    
      "
    
      )
os.mkdir (dirname1)
dirname2 
    
      =
    
       dirname1 
    
      +
    
       
    
      "
    
      .copy
    
      "
    
      

    
      print
    
       dirname1, 
    
      "
    
      =>
    
      "
    
      , dirname2


    
      #
    
      拷目录
    
      

    
      os.system (
    
      "
    
      xcopy /s %s %s
    
      "
    
       
    
      %
    
       (dirname1, dirname2))


    
      if
    
       os.path.isdir (dirname2): 
    
      print
    
       
    
      "
    
      Success
    
      "
   
     

2. shutil.copy和shutil.copytree

   
     

    
      
    
      import
    
       os

    
      import
    
       shutil

    
      import
    
       tempfile

filename1 
    
      =
    
       tempfile.mktemp (
    
      "
    
      .txt
    
      "
    
      )
open (filename1, 
    
      "
    
      w
    
      "
    
      ).close ()
filename2 
    
      =
    
       filename1 
    
      +
    
       
    
      "
    
      .copy
    
      "
    
      

    
      print
    
       filename1, 
    
      "
    
      =>
    
      "
    
      , filename2


    
      #
    
      拷文件
    
      

    
      shutil.copy (filename1, filename2)


    
      if
    
       os.path.isfile (filename2): 
    
      print
    
       
    
      "
    
      Success
    
      "
    
      

dirname1 
    
      =
    
       tempfile.mktemp (
    
      "
    
      .dir
    
      "
    
      )
os.mkdir (dirname1)
dirname2 
    
      =
    
       dirname1 
    
      +
    
       
    
      "
    
      .copy
    
      "
    
      

    
      print
    
       dirname1, 
    
      "
    
      =>
    
      "
    
      , dirname2


    
      #
    
      拷目录
    
      

    
      shutil.copytree (dirname1, dirname2)


    
      if
    
       os.path.isdir (dirname2): 
    
      print
    
       
    
      "
    
      Success
    
      "
   
     

3.  win32file.CopyFile

   
     

    
      
    
      import
    
       os

    
      import
    
       win32file

    
      import
    
       tempfile

filename1 
    
      =
    
       tempfile.mktemp (
    
      "
    
      .txt
    
      "
    
      )
open (filename1, 
    
      "
    
      w
    
      "
    
      ).close ()
filename2 
    
      =
    
       filename1 
    
      +
    
       
    
      "
    
      .copy
    
      "
    
      

    
      print
    
       filename1, 
    
      "
    
      =>
    
      "
    
      , filename2


    
      #
    
      拷文件
    
      
#
    
      文件已存在时，1为不覆盖，0为覆盖
    
      

    
      win32file.CopyFile (filename1, filename2, 
    
      1
    
      )
win32file.CopyFile (filename1, filename2, 0)
win32file.CopyFile (filename1, filename2, 
    
      1
    
      )


    
      if
    
       os.path.isfile (filename2): 
    
      print
    
       
    
      "
    
      Success
    
      "
    
      

dirname1 
    
      =
    
       tempfile.mktemp (
    
      "
    
      .dir
    
      "
    
      )
os.mkdir (dirname1)
dirname2 
    
      =
    
       dirname1 
    
      +
    
       
    
      "
    
      .copy
    
      "
    
      

    
      print
    
       dirname1, 
    
      "
    
      =>
    
      "
    
      , dirname2


    
      #
    
      拷目录
    
      

    
      win32file.CopyFile (dirname1, dirname2, 
    
      1
    
      )


    
      if
    
       os.path.isdir (dirname2): 
    
      print
    
       
    
      "
    
      Success
    
      "
   
     

4. SHFileOperation

   
     

    
      
    
      import
    
       os

    
      from
    
       win32com.shell 
    
      import
    
       shell, shellcon

    
      import
    
       tempfile

filename1 
    
      =
    
       tempfile.mktemp (
    
      "
    
      .txt
    
      "
    
      )
open (filename1, 
    
      "
    
      w
    
      "
    
      ).close ()
filename2 
    
      =
    
       filename1 
    
      +
    
       
    
      "
    
      .copy
    
      "
    
      

    
      print
    
       filename1, 
    
      "
    
      =>
    
      "
    
      , filename2


    
      #
    
      拷文件
    
      
#
    
      文件已存在时，shellcon.FOF_RENAMEONCOLLISION会指示重命名文件
    
      

    
      shell.SHFileOperation (
 (0, shellcon.FO_COPY, filename1, filename2, 0, None, None)
)
shell.SHFileOperation (
 (0, shellcon.FO_COPY, filename1, filename2, shellcon.FOF_RENAMEONCOLLISION, None, None)
)
shell.SHFileOperation (
 (0, shellcon.FO_COPY, filename1, filename2, 0, None, None)
)


    
      if
    
       os.path.isfile (filename2): 
    
      print
    
       
    
      "
    
      Success
    
      "
    
      

dirname1 
    
      =
    
       tempfile.mktemp (
    
      "
    
      .dir
    
      "
    
      )
os.mkdir (dirname1)
dirname2 
    
      =
    
       dirname1 
    
      +
    
       
    
      "
    
      .copy
    
      "
    
      

    
      print
    
       dirname1, 
    
      "
    
      =>
    
      "
    
      , dirname2


    
      #
    
      拷目录
    
      

    
      shell.SHFileOperation (
 (0, shellcon.FO_COPY, dirname1, dirname2, 0, None, None)
)


    
      if
    
       os.path.isdir (dirname2): 
    
      print
    
       
    
      "
    
      Success
    
      "
   
     

   
     

      
    不知道有没有其它的了，os.rename不算，那个是移动文件。另外我在测试它们的性能如何。

这里和楼主列出的都一样，没有更多的了 
或者使用Chilkat  http://www.chilkatsoft.com/refdoc/pythonCkFileAccessRef.html

测试结果出来了： 
 测试环境：系统——Win7 RTM，CPU——P4 3.0，MEM——1.5G DDR400，U盘——Kingston 4G 
  
 用4种不同的方法从硬盘拷贝MSDN 2008 SP1（2.37G）到U盘： 
  
 os System      的方法耗时903.218秒 
 shutil         的方法耗时1850.634秒 
 win32file      的方法耗时861.438秒 
 SHFileOperation的方法耗时794.023秒 
  
 另外SHFileOperation是显示对话框的，可以这样用 

     
       

      
        
      
        shell.SHFileOperation (
 (0, shellcon.FO_COPY, filename1, filename2, 
 shellcon.FOF_RENAMEONCOLLISION 
      
        |
      
         \
 shellcon.FOF_NOCONFIRMATION 
      
        |
      
        \
 shellcon.FOF_NOERRORUI 
      
        |
      
         \
 shellcon.FOF_SILENT, None, None)
)
