I've been learning programming, and so far, my weakest point is probably "regular expressions". If you google, you can come across as many correct answers as you want, but at least I want to be able to read what they represent, so I will introduce them in several parts.
| Regular expressions | meaning |
|---|---|
| {n} | Repeat n times |
| {n, m} | Repeat n times. Up to m times |
| [] | Matches any one of the characters in the brackets |
| [-] | -means something like "kara (~)" |
| . | Match any character |
| \ d | Half-width numbers |
I'm sure the reading depends on the combination. It seems necessary to understand the meaning of each one.
