If the reader does not know what function trimws is doing, it can be easily checked. For example, recently, I recently saw a comment like this in the code: trimws(.) # this function trims leading/trailing white spaces – which is redundant.

In general, comments are distracting and do not explain logic as well as the code does. Write only crucial comments! Your comments should not be a dictionary of easily searchable information.Try to think of what can be surprising to the future reader and preempt their confusion. Comment required business logic or exceptions added on purpose.
If some hack was used, then comments might be used to explain what is going on.
Sometimes you are on your own in a project. Also, note that there is not always a code reviewer that can come to the rescue. That is why before sending the code to review, developers need to make sure that the code is as clean as possible. Poorly written code can also harm team morale – code reviewers are frustrated while code creators might feel offended by a huge number of comments. Having a well-established code review process does not change the fact that the developer is responsible for writing good, clean code! Pointing out all of the code’s basic mistakes is painful, time-consuming, and distracts reviewers from going deep into code logic or improving the code’s effectiveness. Read more about how we organize our work in Olga’s blog post on best practices recommended for all data science teams. At Appsilon, we treat code review as a must for every project. It is also a great way to share best practices and distribute knowledge among team members. A clean, readable, and concise codebase is the key to effective collaboration and provides the highest quality value to the client.Ĭode review is a crucial part of maintaining a high-quality code process. Over many years of experience delivering successful projects, I’ve found one common element in each implementation.
