Defining a color in python

I have a question that may be straight forward, or may be impossible to answer, I'm not sure. I'm wondering how I can define a color in python.

For example, I would like to simply do this:

myColor = #920310

However, using the '#' sign in python automatically comments anything following. Is there a way around this? Thank you and sorry if this question is very simple

Depending on how you are planning to use the values, you have many options:

colorString = "#920310"
colorList   = [0x93, 0x03, 0x10] 
colorTuple  = (0x93, 0x03, 0x10)
colorDict   = {
   "R" : 0x93,
   "G" : 0x03,
   "B" : 0x10,
}

Or, if you're planning to have several operations to deal with your color, say convert to different formats, you can define a Color class:

class Color(object):
    def __init__(self, r, g, b):
        self._color = (r,g,b)

    def get_tuple(self):
        return self._color

    def get_str(self):
        return "#%02X%02X%02X" % self._color

    def __str__(self):
        return self.get_str()

    def get_YUV(self):
        # ...

Example usage:

>>> a = Color(0x93, 0x03, 0xAA) # set using hex
>>> print a
#9303AA
>>> b = Color(12, 123, 3) # set using int
>>> print b
#0C7B03

myColor = int('920310', 16) #as an integer (assuming an RGB color in hex)


myColor = '#920310' #as a string


from collections import namedtuple
Color = namedtuple("Color", "R G B")
myColor = Color(0x92, 0x03, 0x10)
#as a namedtuple

There are lots of things you could be looking for, and equally many ways to use it. Ultimately, it depends on how you want to use this color.

If you want it as a string, do 

myColor = '#920310'

If you actually want it to be a Color object, you can do something like

myColor = Color('#920310')

and interpret it in Color's constructor.

If the question is can you make # not be interpreted as a comment, then the answer is no. If # wasn't a comment, it wouldn't be Python any more.

You could define your own, Python-like language where a # after an = wouldn't mean a comment (since that's not valid Python anyway) and it wouldn't break any code, but you wouldn't be able to use the # syntax elsewhere without breaking code.

mycolor = '#<colorcodehere>'

mycolor will be seen as a string, so everything inside the apices will be read (# too)
