monty.shutil module

Copying and zipping utilities. Works on directories mostly.

compress_dir(path, compression='gz')[source]

Recursively compresses all files in a directory. Note that this compresses all files singly, i.e., it does not create a tar archive. For that, just use Python tarfile class.

Parameters
  • path (str) – Path to parent directory.

  • compression (str) – A compression mode. Valid options are “gz” or “bz2”. Defaults to gz.

compress_file(filepath, compression='gz')[source]

Compresses a file with the correct extension. Functions like standard Unix command line gzip and bzip2 in the sense that the original uncompressed files are not retained.

Parameters
  • filepath (str) – Path to file.

  • compression (str) – A compression mode. Valid options are “gz” or “bz2”. Defaults to “gz”.

copy_r(src, dst)[source]

Implements a recursive copy function similar to Unix’s “cp -r” command. Surprisingly, python does not have a real equivalent. shutil.copytree only works if the destination directory is not present.

Parameters
  • src (str) – Source folder to copy.

  • dst (str) – Destination folder.

decompress_dir(path)[source]

Recursively decompresses all files in a directory.

Parameters

path (str) – Path to parent directory.

decompress_file(filepath)[source]

Decompresses a file with the correct extension. Automatically detects gz, bz2 or z extension.

Parameters
  • filepath (str) – Path to file.

  • compression (str) – A compression mode. Valid options are “gz” or “bz2”. Defaults to “gz”.

gzip_dir(path, compresslevel=6)[source]

Gzips all files in a directory. Note that this is different from shutil.make_archive, which creates a tar archive. The aim of this method is to create gzipped files that can still be read using common Unix-style commands like zless or zcat.

Parameters
  • path (str) – Path to directory.

  • compresslevel (int) – Level of compression, 1-9. 9 is default for GzipFile, 6 is default for gzip.

remove(path, follow_symlink=False)[source]

Implements an remove function that will delete files, folder trees and symlink trees

1.) Remove a file 2.) Remove a symlink and follow into with a recursive rm if follow_symlink 3.) Remove directory with rmtree

Parameters
  • path (str) – path to remove

  • follow_symlink (bool) – follow symlinks and removes whatever is in them
