For me that's the issue with this whole example; it kinda misses the woods for the trees. # not interesting (also, use stdlib instead) def extract_url_params(url: str) -> dict[str, str]: params = url.split('?')[1].split('&') return = dict(param.split('=') for param in params) # This is the thing that needs explaining! final_3_param_values = list(extract_url_params(url).values())[-3:] By decomposing the problem in a more natural way, you can entirely direct the reader's attention to the thing that's causing the dissonance. For some reason it's just the the final 3 values they want (both weird requirements). Make that clear from the code!
