ctypes-based Python version of OS X's pbpaste command for Windows.

pbpaste.py

import sys
import ctypes

# This is adapted from code found via:
# http://nullege.com/codes/search/ctypes.windll.user32.OpenClipboard

ctypes.windll.user32.OpenClipboard(0)
pcontents = ctypes.windll.user32.GetClipboardData(1) # 1 is CF_TEXT
data = ctypes.c_char_p(pcontents).value
ctypes.windll.user32.CloseClipboard()

if data is not None:
    sys.stdout.write(data.replace('\r\n', '\n'))

The Windows clip.exe program can be used as an alternative to pbcopy, too.
