Re: [Python-ideas] What about regexp string litterals : re".*" ?
I feel like that borders on a bit too wordy... Personally, I'd like to see something like Felix's regular definitions: http://felix-lang.org/share/src/web/tut/regexp_01.fdoc#Regular_definitions._... -- Ryan (ライアン) Yoko Shimomura > ryo (supercell/EGOIST) > Hiroyuki Sawano >> everyone else http://refi64.com On Mar 29, 2017 3:30 PM, "Abe Dillon" <abedillon@gmail.com> wrote: My 2 cents is that regular expressions are pretty un-pythonic because of their horrible readability. I would much rather see Python adopt something like Verbal Expressions ( https://github.com/VerbalExpressions/ PythonVerbalExpressions ) into the standard library than add special syntax support for normal REs.

I think the use of words instead of symbols is one of the things that makes Python so readable. The ternary operator is done with words: value = option1 if condition else option2 reads almost like English, while: value = condition ? option1: option2; Is just weird. I can read Verbal Expressions very quickly and understand exactly what's going on. If I have a decent IDE, I can write them almost as easily. I see no problem with wordiness if it means I don't have to stare at the code and scratch my head longer, or worse, open a reference to help me translate it (which is invariably the case when I look at regular expressions).

However, a huge advantage of REs is that they are common to many languages. You can take a regex from grep to Perl to your editor to Python. They're not absolutely identical, of course, but the basics are all the same. Creating a new search language means everyone has to learn anew. ChrisA
