大家好，又见面了，我是你们的朋友全栈君。
不知道在什么时候看到个好帖，觉得好就移过来了，学习学习。。。
1. os.system
- Python code
-
import os import tempfile filename1 = tempfile.mktemp ( " .txt " ) #产生临时文件或目录，tempfile.mktemp(suffix='',prefix='tmp'，dir=None) 产生的文件名或目录，默认就是函数里的参数。
-
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)) #DOS下，拷贝目录命令xcopy if os.path.isdir (dirname2): print " Success "

2. shutil.copy和shutil.copytree
- Python code
-
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
- Python code
-
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
- Python code
-
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 "
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SHFileOperation能操作网络上的文件
如果你想将本地文件复制到192.168.1.99
那么只要在192.168.1.99上共享123目录
然后将pTo设置为http://www.cnblogs.com/lovemo1314/admin/file://192.168.1.99/123
就可以了
但不要设置为http://www.cnblogs.com/lovemo1314/admin/file://192.168.1.99/
- Python code
-
shell.SHFileOperation ( -
(0, shellcon.FO_COPY, filename1, filename2, -
shellcon.FOF_RENAMEONCOLLISION |
-
\ shellcon.FOF_NOCONFIRMATION |\
-
shellcon.FOF_NOERRORUI | \
-
shellcon.FOF_SILENT, None, None)) -
-
FOF_SILENT //不产生正在复制的对话框
FOF_NOCONFIRMMKDIR//如果目的目录不存在，就默认创建
FOF_NOCONFIRMATION //不出现确认文件替换对话框(Confirmation Dialog)(默认替换原来的文i件)
FOF_NOERRORUI//不出现错误对话框
最好不要同时使用FOF_NOERRORUI,FOF_NOCONFIRMMKDIR,因为FOF_NOCONFIRMMKDIR屏蔽了missing directory Error
但FOF_NOERROR又屏蔽了missing directory Error,那么在同时使用FOF_NOERRORUI,FOF_NOCONFIRMMKDIR
