I am trying to build a regex in Python for the following pattern

Example: 123456B01R02 or Example: 263956A01R04

I am completely new to Regex and struggeling big time. I was trying 6[0-9]1[A-D]2[0-9]R2[0-9] but of course it does not work.

Could anyone please give me some kickstart? Thanks in advance!

`[0-9]` matches a digit, `[0-9]{6}` matches six digits. Do not forget to use the right `re` method: if you want to only match strictly that string format use `re.fullmatch`. – Wiktor Stribiżew Nov 08 '21 at 15:27
so then [0-9]{6}[A-D][0-9]{2}[R][0-9]{2} would be correct? – Dennis Nov 08 '21 at 15:32
Did you try it? – Wiktor Stribiżew Nov 08 '21 at 15:33
I tried the two examples and they match. Questioning myself if it matches all cases. How can I be sure? – Dennis Nov 08 '21 at 15:35

Looks good for the moment. I'll leave it like that. Thanks a lot! – Dennis Nov 08 '21 at 15:44
/[0-9]{6}[A-D][0-9]{2}R[0-9]{2}/ – Alexis Leloup Nov 08 '21 at 16:00
