I would make the signature
def colorPrint(*color_items):
This was the caller doesn't need to enclose the arguments in a list,
it would be called like
colorPrint(('text', 0), ('more text', 1))
Another way to do this would be to make an object to hold the color
value and a print function that special cases it. A sketch:
class Style(object):
def __init__(self, style):
self.style = style
def set_style(self):
# Set the text color according to self.style
def colorPrint(*items):
for item in items:
if isinstance(item, Style):
item.set_style()
else:
print item,
Now you can say
colorPrint(Style(0), 'some text', Style(1), 'some text in a different color')
