I have two list which have different value. I tried to put the a list in an organized format with g.split. Although it work fine on the a list, but it cant filter b list properly a

Solution 1:

There are issue with your data format and regex, I am not that good at regex but this works on me.

out = []
for v in b:
    regex_list = re.findall(r"^(.*?\(.*?\))\n", v.replace('.\n', '\n').replace('.',':'), flags=re.M)
    for g in regex_list:
        print(g)

    print(*out[0])
