Splitting text that is already in memory

splitlines() returns an independent list without line endings. Pass True to keep the original endings. A final newline does not add an extra empty line, and empty text produces an empty list. Unlike file reads, this method also recognizes Unicode line/paragraph separators and the other Python-style text line boundaries.

def main() -> Result[(), AllocError | IoError]:
    print("first\r\n\nlast\n".splitlines()?)?
    print("first\r\nlast".splitlines(True)?)?
    print("".splitlines()?)?
    Ok(())

["first", "", "last"]
["first\r\n", "last"]
[]
