Keep it short and simple

Python has amazing functionalities which allow us to write 21st century code. For example, we can collect functions and parameters in lists and the call them from a loop. While this is super cool from a programming point of view, it might not be easy to read code. The recommendation is: Keep it short and simple (KISS).

import numpy as np
from skimage.io import imread, imshow
from napari_segment_blobs_and_things_with_membranes import threshold_otsu, gaussian_blur, label

Exercise

As an example, there are two code sections below. Without running the code - do you think both do the same?## Exercise: Without running the code - do you think both do the same?

image = imread("../../data/blobs.tif")

# define a list of functions and a corresponding list of arguments
functions = [gaussian_blur, threshold_otsu, label]
argument_lists = [[.5], [], []]

# go through functions and argument lists pair-wise
for function, argument_list in zip(functions, argument_lists):
    # execute function with given arguments
    image = function(image, *argument_list)

result1 = image
imshow(result1)

image = imread("../../data/blobs.tif")

blurred = gaussian_blur(image, 5)
binary = threshold_otsu(blurred)
labels = label(binary)

result2 = labels

imshow(result2)

If you are not sure, you can also directly check if the results are equal:

np.all(result1 == result2)
