在包含一个分组的模型中转换单个模型，该分组具有将用作标头的键

# 示例代码：保留分组结构的转换
original_data = {
    "group1": {"key1": "value1", "key2": "value2"},
    "group2": {"keyA": "valueA"}
}

def convert_data(data):
    converted_data = {}
    for group, items in data.items():
        converted_data[group] = {key: process_value(value) for key, value in items.items()}
    return converted_data

def process_value(value):
    # 这里可以添加具体的转换逻辑
    return value

converted_data = convert_data(original_data)
print(converted_data)

# 示例代码：标头键映射
header_mapping = {
    "src_key1": "dst_key1",
    "src_key2": "dst_key2",
    # ...
}

def map_headers(data, mapping):
    mapped_data = {}
    for src_key, dst_key in mapping.items():
        if src_key in data:
            mapped_data[dst_key] = data[src_key]
    return mapped_data

mapped_data = map_headers(original_data, header_mapping)
print(mapped_data)
