Import shutil # read a file and write to another file

F1=open ("text.txt")

F2=open ("Note 1", "w")

Shutil.copyfileobj (F1 and f2)

Shutil.copyfile (Note1, Note2) # copy file

Shutil.copystat ("text.txt", "Note 2") # copy permission does not create a new file

Shutil.copy () # copy files and permissions

Shutil.copy2 () # copy files and status information

Shutil.rmtree ("new_test") # Delete file directory

Shutil.make_archive ("D:/timetttttt_tp", "zip", "C:\ Users\ arce.PyCharmCE2017.2") # need to be compressed, compressed format, where to put compressed files

Make_archive (base_name, format, root_dir=None, base_dir=None, verbose=0, dry_run=0, owner=None, group=None, logger=None)

Import zipfile

Z=zipfile.ZipFile ("os_txt.zip", "w") # compress files separately (create a package and put the files in)

Z.write ("os.txt.py")

Print ("- -")

Z.write ("Notes 2")

Z.close ()

Z=zipfile.ZipFile ("os_txt.zip", "r") # decompress

Z.extractall ()

Z.close ()

#

Import tarfile

Tar=tarfile.open ("name.tar", "w")

Tar.add (r "E:\ 2018.4.9\ Test", arcname= "Test")

Tar.add (r "E:\ 2018.4.9\ Module 3", arcname= "Module 3")

Tar.close ()

Tar=tarfile.open ("name.tar", "r")

Tar.extractall () # fill in the parentheses here where to decompress (path)

Tar.close ()

Import os

Print (os.path.abspath ("name.tar")) # View file path
