问题 I'm trying to build a corpus from the .txt file found at this link. I believe the instances of \xad are supposedly 'soft-hyphens', but do not appear to be read correctly under UTF-8 encoding. I've tried encoding the .txt file as iso8859-15 , using the code: with open('Harry Potter 3 - The Prisoner Of Azkaban.txt', 'r', encoding='iso8859-15') as myfile: data=myfile.read().replace('\n', '') data2 = data.split(' ') This returns an array of 'words', but '\xad' remains attached to many entries in

问题 I'm trying to use str_replace_all to replace many different values (i.e. "Mod", "M2", "M3", "Interviewer") with one the consistent string (i.e. "Moderator:"). I'm doing this with multiple different categories, and I want avoid having to write each unique value out as there are a lot. So I made a tibble consisting of all the unique values that I want to make standardized and read it in and then pulled out each column (there are 5 but only 2 shown for simplicity) to make them into vectors:

问题 I use RegExp and "string".match very rarely so I'm not so sure how to use them for some little bit complex things.Here's what I would like to do and don't know how to do it.
