First, you will be implementing the invert function. (Reminder: all of these functions take in a three-dimensional list, and return a three-dimensional list: it's up to you whether to create a new list or alter the original). This function performs a color inversion, as though you were producing a negative of a photo. Recall that each color component in every pixel is an integer between 0 and 255, inclusive. In every pixel, for each of the three color components, if the original value for the component was x, to invert the color you must set it to 255-X.

First, you will be implementing the invert function. (Reminder: all of these functions take in a three-dimensional list, and return a three-dimensional list: it's up to you whether to create a new list or alter the original). This function performs a color inversion, as though you were producing a negative of a photo. Recall that each color component in every pixel is an integer between 0 and 255, inclusive. In every pixel, for each of the three color components, if the original value for the component was x, to invert the color you must set it to 255-X. Hint: Go look at the swap_red_blue example near the bottom of your hw06.py template if you're uns unsure how to loop through the pixels and access specific colors at each pixel. Examples: >>> invert([[[127, 127, 127], [0, 0, 0]], [[255, 255, 0], [50, 128, 255]], [[0, 0, 255], [0, 255, 0]], [[255, 0, 0], [255, 255, 255]]]) [[[128, 128, 128], [255, 255, 255]], [[0, 0, 255], [205, 127, 0]], [[255, 255, 0], [255, 0, 255]], [0, 255, 255], [0, 0, 0]]] >>> invert([[[36, 155, 90], [63, 208, 208], [151, 3, 14]], [[53, 204, 53], [99, 103, 10], [94, 138, 216]]]) [[[219, 100, 165], [192, 47, 47], [104, 252, 241]], [[202, 51, 202], [156, 152, 245], [161, 117, 39]]] (note that the highlighting and the new line for each row are for clarity purposes only and will not be present in the actual console output, but the numbers should be correct)
