Color Dictionary

Nov 10th, 2006

I have a color data file that gives the color name and its RGB values, for instance like this:

 Help with Code Tags 
 Python Syntax (Toggle Plain Text) 
 
red RGB(255,0,0)
green RGB(0,128,0)
blue RGB(0,0,255)
brown RGB(165,42,42)
gold RGB(255,215,0)
maroon RGB(128,0,0)
 
red RGB(255,0,0)
green RGB(0,128,0)
blue RGB(0,0,255)
brown RGB(165,42,42)
gold RGB(255,215,0)
maroon RGB(128,0,0)

I like to create a color dictionary from this file that looks like this:

 Help with Code Tags 
 Python Syntax (Toggle Plain Text) 
 
{'red': (255,0,0), 'green': (0,128,0), 'blue': (0,0,255), ...}
 
{'red': (255,0,0), 'green': (0,128,0), 'blue': (0,0,255), ...}

How can I best do that?

If the data are packaged as neatly as your file shows, then I would recommend using .split() and then eval() to convert the parenthesized string to a tuple:

[php]
f = open("my_data")
colors = {}
for line in f:
line = line.strip('\n')
name, value = line.split(' RGB ')
colors[name] = eval(value) # converts string to tuple
[/php]
