Question

I’d like to split the following string on letters:

1234B

There are always only ever 4 digits and one letter. I just want to split those out.

Here is my attempt, I think I have the method right and the regex matches the number but I dont think my syntax or my regex is pertinent to the problem Im attempting to solve.

"1234A".split(/^\d{4}/)

Answer 1

If there are always 4 digits and 1 letter, there’s no need to use regular expressions to split the string. Just do this:

str = "1234A"
digits,letter = str[0..3],str[4]
