Let's automate the boring parts of the code review. list_primes.py 00:00:00.000000 +0000 +++ list_primes.py 00:00:00.000000 +0000 -1,17 +1,19 # list_primes.pyĬode review can be split in two parts: the interesting part where you solve big picture issues and the mundane parts where you identify non-idiomatic snippets and code style violations. Running the following command creates two files, Pipfile and Pipfile.lock, in the root of the repo and installs Black as a dev dependency.

#Black python formatter install

So let's install Black, while also taking the opportunity to set up some first-class dependency management with a tool I personally love, Pipenv. What's neat is that it is pretty opinionated and can't be configured much, making it ideal for automation. It is capable of automatically reformatting your Python files, fixing all code style violations.

Extraneous space before function parenthesisīlack is a popular code formatter for Python.

Don't get me wrong, it works, but it's not good. There are a lot of problems with this script. # list_primes.py def is_prime (number ) : for i in range ( 2, number ) : if number %i = 0 : return False return True def list_primes (upper ) : for number in range ( 2, upper ) : if is_prime (number ) : print ( F" is prime" )

#Black python formatter Patch

These suggestions can improve performance, incorporate new language features, patch security oversights, or correct code style. Code reviews go a long way towards this goal.Ĭode review is the process where developers more experienced than yourself read through your code and suggest improvements that could make it better. Identifying the quality of code is an intuition that is honed over time, through practice and experience. Those are two MIT professors with pretty solid credentials. Programs are meant to be read by humans and only incidentally for computers to execute. All we have are some abstract guidelines such as readability: That's because there are no rules set in stone about what makes code good or bad. When we talk of good code, the word 'good' is vague by design.

The former is a skill while the latter is an art form, and this difference distinguishes great programmers from the crowd. Writing code that works and writing good code are two very different things. I wish it had done this, rather than essentially codify the author's style. But I also think that's an opportunity, rather than having to guess at what is good, there's a wealth of prior art to look at. Black is in a challenging position of coming into a community with a lot of existing code and customs, and I get that. I totally believe using a formatter is good practice. I'd prefer to use yapf, but last I checked it still crashes on "f-strings". I super dislike black's formatting, and I think it's really rare to actually see it in codebases.
