If your data literally looks like the example (the fields never contain '||' and are always quoted), and you can tolerate the quote marks, or are willing to slice them off later, just use .split

['"1234"', '"abcd"', '"a1s1"']
>>> list(s[1:-1] for s in '"1234"||"abcd"||"a1s1"'.split('||'))
['1234', 'abcd', 'a1s1']

csv is only needed if the delimiter is found within the fields, or to delete optional quotes around fields
