Expanding an alphanumeric range given a list-CodePudding

I have a list of alphanumeric items:

values=['1111X0-1111X3', 'A111X0-A111X3',...., ]

I would like to expand the last digit of every item in this list such that:

values_output = ['111X0', '111X1', '111X2', '111X3', 'A111X0', 'A111X1', 'A111X2', 'A111X3',...' ',...]

I found this answer on a similar post that uses regex:

import re

lst = ['4276-4279', 'I69-I71', 'V104-V112', '11528']
new = []
for l in lst:
    m = re.match(r'^([A-Z]*)(\d )-\1(\d )$', l)
    if m:
        new  = [m.group(1)   str(i) for i in range(int(m.group(2)), int(m.group(3)) 1)]
    else:
        new  = [l]

print(new)

However I could not figure out a pattern to match the items on my list.

Any input is greatly appreciated!

CodePudding user response：

You can use

re.search(r'^(\w ?)(\d )-\1(\d )$', l)

See the Python demo.

Details:

^ - start of string
(\w ?) - Group 1: any one or more word chars as few as possible
(\d ) - Group 2: one or more digits
- - a hyphen
\1 - Group 1 value
(\d ) - Group 3: one or more digits
$ - end of string.
