如何从此列表中检索列数据

def retrieve_column_data(data, column_name, target_value):
    result = []
    column_index = data[0].index(column_name)  # 获取目标列的索引

    for row in data[1:]:  # 遍历每一行数据
        if row[column_index] == target_value:  # 检查目标列的值是否匹配
            result.append(row)  # 将匹配的行添加到结果集中

    return result

# 示例数据
data = [
    ['Name', 'Age', 'Gender'],
    ['John', '25', 'Male'],
    ['Emily', '30', 'Female'],
    ['Michael', '35', 'Male'],
    ['Jessica', '28', 'Female']
]

# 检索名字为John的行数据
result = retrieve_column_data(data, 'Name', 'John')
print(result)
