Getting started with Python: Common modules-shutil Modules

Advanced files, folders, Compression pack processing modules

Shutil.copyfileobj (FSRC, fdst[, length])
Copy the contents of a file to another file

Mport shutilshutil.copyfileobj (Open (' old '), open (' New ', ' W '))

　　

Shutil.copyfile (SRC, DST)
Copy files

Shutil.copyfile (' F1.log ', ' F2.log ')     # Copy files, destination files need not exist

　　

Shutil.copymode (SRC, DST)
Copy permissions only. Content, group, user are not changed

Shutil.copymode (' F1.log ', ' F2.log ')    # The destination file must exist

　　

Shutil.copystat (SRC, DST)
Copy only the status information, including: mode bits, Atime, mtime, Flags

Shutil.copystat (' F1.log ', ' F2.log ')      # The destination file must exist

　　

Shutil.copy (SRC, DST)
Copying files and Permissions

Shutil.copy (' F1.log ', ' F2.log ')

　　

Shutil.copy2 (SRC, DST)
Copying files and status information

Shutil.copy2 (' F1.log ', ' F2.log ')

　　

Shutil.ignore_patterns (*patterns)
Shutil.copytree (SRC, DST, Symlinks=false, Ignore=none)
Recursive go-to-copy folder

Shutil.copytree (' Folder1 ', ' Folder2 ', ignore=shutil.ignore_patterns (' *.pyc ', ' tmp* ')) #目标目录不能存在, Note for Folder2 directory parent directory to have writable permissions, ignore means to exclude

　　

Shutil.rmtree (path[, ignore_errors[, OnError])
To delete a file recursively

Shutil.rmtree (' Folder1 ')    # recursively go to delete files directory

　　

Shutil.move (SRC, DST)
To move a file recursively, it is like the MV command, which is actually renamed.

Shutil.move (' Folder1 ', ' Folder2 ')       # Move folder, like MV

　　

Shutil.make_archive (base_name, Format,...)
Create a compressed package and return the file path, for example: Zip, tar

• Base_name: The file name of the compressed package, or the path to the compressed package. Only the file name is saved to the current directory, otherwise saved to the specified path,

such as Data_bak = Save to Current path
such as:/tmp/data_bak = Save to/tmp/

• Format: Compressed package type, "Zip", "tar", "Bztar", "Gztar"
• Root_dir: Folder path to compress (default current directory)
• Owner: User, default Current user
• Group: Groups, default current group
• Logger: Used to log logs, usually logging. Logger Object

ret = shutil.make_archive (' My_proj_bak ', ' Gztar ', root_dir= ' my_proj ')

　　

Shutil Processing of compressed packets is done by calling the ZipFile and Tarfile two modules, in detail:
ZipFile Compression & Decompression

Import Zipfilez = ZipFile. ZipFile (' Log.zip ', ' W ') z.write (' F1.log ') z.write (' F2.log ') z.close ()

　　

z = zipfile. ZipFile (' Log.zip ', ' R ') Z.extractall (path= '. ') Z.close ()

　　

Tarfile Compression & Decompression

Import Tarfilet = Tarfile.open (' Log.tar ', ' W ') t.add (' F1.log ', arcname= ' F1.bak ') t.close ()
