red_filter_pixel

Let’s start by coding a red filter for a single pixel. Remember, pixels are given as a 3-tuple, which is an immutable data structure. Meaning, you will need to generate a new tuple! Create a function called red_filter_pixel(px) which takes as an argument a RGB 3-tuple p and returns an RGB 3-tuple that has been red filtered, i.e., has non-red parts set to 0.

Here is a pixel with the color values (200,250,150):

And here it is after being red filtered, with colors values (200,0,0):
