I’m coding something for my job to copy directories and then use regex to make all the filenames uniform. I’m an undergrad student programmer for my university and I’m not sure what a professional coder would consider reasonable in this case. My job is mostly to implement mathematical research. The current assignment is outside what I’ve been doing and seems like it would be really useful to have some of the functions available in case I (most likely) encounter a similar assignment at some point in my career in the future. It’s going to be really useful because the current filenames are so screwed right now that the admin assistants can’t really keep up (and even trying to do so might just cause more human error). I’m thinking that it may not overall be useful outside the current assignment because the regex will be so customised to the way the file are incorrectly named.
