Checksum Python Script

Added a Python script to calculate or verify a file’s checksum/hash/message digest (MD5, SHA-1, SHA-256, etc.) to my public Mercurial code repository of miscellaneous stuff.

The file is and lives (of course) in the Python section of the repo.

It assumes that you have Python 3.x installed and it uses Python’s own argparse and hashlib modules.

It comes also with a simple Tkinter-based GUI frontend (gui.pyw).
