Guido van Rossum be19ed77dd Fix most trivially-findable print statements.
There's one major and one minor category still unfixed:
doctests are the major category (and I hope to be able to augment the
refactoring tool to refactor bona fide doctests soon);
other code generating print statements in strings is the minor category.

(Oh, and I don't know if the compiler package works.)

# tk common colour chooser dialogue
#
# this module provides an interface to the native color dialogue
# available in Tk 4.2 and newer.
#
# written by Fredrik Lundh, May 1997
#
# fixed initialcolor handling in August 1998
#
#
# options (all have default values):
#
# - initialcolor: colour to mark as selected when dialog is displayed
# (given as an RGB triplet or a Tk color string)
#
# - parent: which window to place the dialog on top of
#
# - title: dialog title
#
