Code metrics are a popular way to analyse the complexity of our software. For some reason, we are attracted to single-figure summaries of quality, whether it’s lines of code, cyclomatic complexity, or the Pylint score. Personally, I think using these are about as valuable as judging another person based on one of their visible or measurable characteristics. Which is to say, an okay metric might get the conversation started, but it won’t help you know them. That takes time and effort, humility, seeking to understand their background, and changing your mind about previous assumptions when something about them challenges you.
