Creating and removing files and directories with Python os module
"""This is done with the os module, which has lots of methods for handling files and dirs.
<http://docs.python.org/lib/os-file-dir.html>
Effbot's page on the os module: <http://effbot.org/librarybook/os.htm>
The shutil module is useful here also: <http://docs.python.org/lib/module-shutil.html>
"""
import os
# Make a new file.
# Simply opening a file in write mode will create it, if it doesn't exist. (If
# the file does exist, the act of opening it in write mode will completely
# overwrite its contents.)
try:
f = open("file.txt", "w")
except IOError:
pass
# Remove a file.
try:
os.remove(temp)
except os.error:
pass
# Make a new directory.
os.mkdir('dirname')
# Recursive directory creation: creates dir_c and if necessary dir_b and dir_a.
os.makedirs('dir_a/dir_b/dir_c')
# Remove an empty directory.
os.rmdir('dirname')
os.rmdir('dir_a/dir_b/dir_c') # Removes dir_c only.
# Recursively remove empty directories.
# removedirs removes all empty directories in the given path.
os.removedirs('dir_a/dir_b/dir_c')
# Neither rmdir or removedirs can remove a non-empty directory, for that you need the further file
# operations in the shutil module.
# This removes the directory 'three' and anything beneath it in the filesystem.
import shutil
shutil.rmtree('one/two/three')
