if __name__ == '__main__': cartoon('2.jpg', edge='Canny')

As an AI language model, I do not have access to the function or module `cartoon` and the image file `2.jpg`. However, I can explain what the code is doing.

The code is checking whether the script is being run directly (as opposed to being imported as a module) using the `__name__` variable. If it is being run directly, the `cartoon` function is called with the argument `'2.jpg'` for the image file and the parameter `edge='Canny'` to specify the edge detection algorithm to use. The `cartoon` function presumably applies a cartoon filter to the image, which can be customized with various parameters including the edge detection algorithm.
