The unreasonable effectiveness of f‍-‍strings and re.VERBOSE

... in which we look at one or two ways to make life easier when working with Python regular expressions. tl;dr: You can compose verbose regular expressions using f‍-‍strings. Here's a real-world example – instead of this: 1pattern = r"((?:\(\s*)?[A-Z]*H\d+[a-z]*(?:\s*\+\s*[A-Z]*H\d+[a-z]*)*(?:\s*[\):+])?)(.*?)(?=(?:\(\s*)?[A-Z]*H\d+[a-z]*(?:\s*\+\s*[A-Z]*H\d+[a-z]*)*(?:\s*[\):+])?(?![^\w\s])|$)"

f‍文字列とre.VERBOSEで長い正規表現を効率的に書けるらしい。そんなに長い正規表現を書くことが個人的にはあまりないが。
