检测并替换缩写：基于嵌套列表与字典的文本处理需求

我有如下格式的嵌套列表：

Mylist = [["where is USA?", "How are you in UK?"], 
          ["I need it", "OMG you scared me"]]

同时还有一个缩写映射字典：

Abbr = {"USA": "United States of America", 
        "UK": "United Kingdom", 
        "ASAP": "As soon as possible", 
        "OMG": "Oh my god"}

需要遍历该嵌套列表，识别其中的缩写并进行替换，最终生成包含原句和替换后句子的新列表，预期结果如下：

[["where is USA?", "where is United States of America?",
  "How are you in UK?", "How are you in United Kingdom?"],
 ["I need it", "OMG you scared me", "Oh my god you scared me"]]

通过嵌套遍历列表结合字符串替换即可实现需求，核心逻辑如下：

• 外层遍历嵌套列表的每个子列表
• 对每个句子，先将原句加入结果集合
• 检查句子中是否存在缩写字典内的缩写，若存在则替换并将新句子加入结果

实现代码：

# 原始嵌套列表
Mylist = [["where is USA?", "How are you in UK?"], 
          ["I need it", "OMG you scared me"]]
# 缩写映射字典
Abbr = {"USA": "United States of America", 
        "UK": "United Kingdom", 
        "ASAP": "As soon as possible", 
        "OMG": "Oh my god"}

# 初始化结果列表
processed_list = []

# 遍历每个子列表
for sublist in Mylist:
    temp_sublist = []
    for sentence in sublist:
        # 添加原句到临时子列表
        temp_sublist.append(sentence)
        # 遍历缩写字典，查找并替换
        for abbr, full_form in Abbr.items():
            if abbr in sentence:
                replaced_sent = sentence.replace(abbr, full_form)
                temp_sublist.append(replaced_sent)
                # 每个句子仅处理第一个匹配的缩写（符合示例逻辑）
                break
    processed_list.append(temp_sublist)

# 输出处理后的列表
print(processed_list)

执行代码后输出与预期完全一致：

[["where is USA?", "where is United States of America?", "How are you in UK?", "How are you in United Kingdom?"], ["I need it", "OMG you scared me", "Oh my god you scared me"]]

若需要将所有句子翻译成中文，可新增翻译映射并生成中文结果，示例代码如下：

# 示例句子中英文翻译映射
trans_map = {
    "where is USA?": "美国在哪里？",
    "where is United States of America?": "美利坚合众国在哪里？",
    "How are you in UK?": "你在英国过得怎么样？",
    "How are you in United Kingdom?": "你在大不列颠及北爱尔兰联合王国过得怎么样？",
    "I need it": "我需要它",
    "OMG you scared me": "我的天，你吓到我了",
    "Oh my god you scared me": "哦我的天，你吓到我了"
}

# 生成中文结果列表
chinese_result = []
for sublist in processed_list:
    chinese_sublist = [trans_map[sent] for sent in sublist]
    chinese_result.append(chinese_sublist)

print(chinese_result)

运行后输出中文结果：

[["美国在哪里？", "美利坚合众国在哪里？", "你在英国过得怎么样？", "你在大不列颠及北爱尔兰联合王国过得怎么样？"], ["我需要它", "我的天，你吓到我了", "哦我的天，你吓到我了"]]
