File Compression Lab/HW - Week 2

[jwasserzug]

This week we went over file compression and the use of modules, including the zipfile, zlib and os modules.

The best solution for each assignment below will be added to our ASG Python Library (http://asg.ise.com/tap/ASG_Library_Keywords_Docs.html). A combination between the cleanest code, the most user friendly output and best functionality will determine the winners.

Lab Assignment:

Create a function called 'compress_file_using_zip' that takes in
    two arguments: directory, filename
    Use os.listdir() to search through the specified directory
    Verify the requested filename is found by os.listdir()
    Create a Zipfile object to create the zipfile
    The zipfile name should be the filename + .zip extension
    Print only three lines if successful:
        1) One line introducing the function
        2) Once you find the file to compress, print:
               Compress file: <filename>
        3) Once done compressing file, print:
               Created zip archive: <zipfile name>
    Print only two lines if failed:
        1) One line introducing the function
        2) If the file was not found, print:
               Did not find <DIR+FILENAME> to compress
    Return True inside conditional if successful
    Return False inside conditional if failed

Homework Assignment:

Create a new function called: 'compress_files_by_extension_using_zip'.
- This function will take in 3 arguments: directory, extension, archive_name
- This function will search through the specified 'directory' and compress all files of the 
specified 'extension' using zip.  The name of this zip archive will be specified by the 
'archive_name'.

BONUS Assignments:

Create a new function called: 'compress_directory_using_zip'
- This function will take 2 arguments: directory, archive_name
- This function will compress the specified directory and store it as a zip file according 
to the specified 'archive_name'. If 'archive_name' is not specified, the zip archive should 
be: folder+'.zip'

Create a new function called: 'compress_files_by_size_using_zip'
- This function will take 3 arguments: directory, size, archive_name
- This function will compress all files in the specified 'directory' which are greater than 
or equal to the 'size' specified by the user. The name of the zip archive will be determined 
by 'archive_name'
