Hi I have a string that I want to parse with Python.
I am new to regex, so really appreciate help.

```
ABC_XYZ::A_BCD_XYZ_C9_KDFJ_7011_1_11_14

```

Output `C9` : Always starts with letter and a digit

Output `7011`: Always 4 or more digits

Output `1, 11, 14`: Always at the end of the string. One or two digits. May have more than 3.

Update.

I was using `[^_]+` and it parses everything '\_'. I wanted just those matches.
