如何从12个不同的列中提取前三个值并返回相关的行名？

def extract_top_three_values(data):
    columns = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L']
    rows = range(2, len(data) + 1)
    result = {}

    for column in columns:
        values = []
        for row in rows:
            value = data[column + str(row)]
            values.append(value)
        values.sort()
        top_three_values = values[:3]

        top_three_rows = []
        for row in rows:
            if data[column + str(row)] in top_three_values:
                top_three_rows.append('Row ' + str(row))

        result[column] = top_three_rows

    return result
