py7file 0.7.4 (beta)

Convenient File Handling Library

Installation

Use easy_install or pip:

pip install py7file

Usage

Here some hopefully self explaining examples of Py7File usage:

from py7file import Py7File

the_file = Py7File('a_file.txt')

# Copy and Move
copied_file = the_file.copy('d_file.txt')  # copied_file is also a Py7file
the_file.move('moved_file.txt')  # moves the file and mutates the reference

# Backup and Restore
the_file.backup()  # creates a_file_backup_001.txt
the_file.backup()  # creates a_file_backup_002.txt
the_file.delete()  # removes a_file.txt from disk (ups...)
the_file.restore() # recovers file from a_file_backup_002.txt

# Unzip and Rezip
zfile = Py7File('a_file.zip')
zfile.unzip() # creates a folder a_file_unzipped with contents of zipfile
zfile.rezip() # repackages subfolder a_file_unzipped to a_file.zip

See test_py7file.py for more examples.

Testing

Py7File is tested against python 2.6 and 2.7

To run the tests:

python test_py7file.py

Status

Well I am using this this file handling library quite extensivly myself and i got no complaints so far ;). Still please consider this Beta and use at your own risk...

Background

As I started learning programming with python I found the different modules for handling files very confusing and cumbersome to use. While writing my first scripts I found myself writing os.path.join(...) way to often. I still keep mixing up os and shutil based file operations like copy, move, rename. So I started this little module to make things easier...
