将一个列表中特定数量的元素替换为另一个列表中的元素

def replace_elements(original_list, replace_list, replace_count):
    new_list = []
    replaced = 0

    for element in original_list:
        if replaced < replace_count and element in replace_list:
            new_list.extend(replace_list)
            replaced += 1
        else:
            new_list.append(element)

    return new_list

# 示例用法
original_list = [1, 2, 3, 4, 5]
replace_list = [6, 7, 8]
replace_count = 2

new_list = replace_elements(original_list, replace_list, replace_count)
print(new_list)
