For example, based on the original code:

    recs = int(input())
    od = OrderedDict()
    items = []

    for _ in range(recs):
        file_input = sys.stdin.readline().strip()
        m = re.search(r"(\w.+)\s+(\d+)", file_input)
        if m: items.append(m.group(1, 2))

    od = OrderedDict(map(lambda item: (item[0], 0), items))
    for item in items: od[item[0]] += item[1]
