Enumerate clipboard formats with Python and Pywin32

clipformats.py

import win32clipboard

formats = {val: name for name, val in vars(win32clipboard).items() if name.startswith('CF_')}

def format_name(fmt):
    if fmt in formats:
        return formats[fmt]
    try:
        return win32clipboard.GetClipboardFormatName(fmt)
    except:
        return "unknown"

win32clipboard.OpenClipboard(None)

fmt = 0
while True:
    fmt = win32clipboard.EnumClipboardFormats(fmt)
    if fmt == 0: break
    print('{:5} ({})'.format(fmt, format_name(fmt)))

win32clipboard.CloseClipboard()

Wouldn't it make more sense to use vars rather than dir here?

You're right. I edited the gist.
