A line of code should do <6 things.
- human short-term & working memory can only cope with upto 6 pieces of info simultaneously
# bad map(lambda x: x.split('='), s.split('?').split('&')[-3:])
# good url_query_string = s.split('?') query_params = url_query_string.split('&')[-3:] map(lambda x: x.split('='), query_params)
The article begins by implying
x, y = 2, 7 is bad. I disagree. I am against blanket-banning legitimate language features. Such bans miss the point. The point is to minimise time-to-comprehend. Everything needs to be considered on a case-by-case basis.
Highly human-readable, brilliant inlining of a single-use
class TimeWindow(start, stop):
start, end = 2, 7 # time window in hours max_retries = 1 # unrelated to above, so separate line
