-# Model Card for Model ID
+# Python Code Tokenizer
 
-<!-- Provide a quick summary of what the model is/does. -->
+专门针对 Python 代码优化的分词器，基于 GPT-2 tokenizer 训练而成。
 
+## 模型详情
 
+### 模型描述
 
-## Model Details
+这是一个专门针对 Python 代码优化的分词器，通过在大规模 Python 代码数据集上训练得到，能够更好地理解和处理 Python 语法结构。
 
-### Model Description
+- **基础模型:** GPT-2 Tokenizer
+- **模型类型:** BPE (Byte Pair Encoding) Tokenizer
+- **语言:** Python 代码
+- **词汇表大小:** 52,000 tokens
+- **许可证:** MIT
+- **训练数据:** CodeParrot Clean Dataset
 
-<!-- Provide a longer summary of what this model is. -->
+### 模型来源
 
-This is the model card of a 🤗 transformers model that has been pushed on the Hub. This model card has been automatically generated.
+- **基础分词器:** `openai-community/gpt2`
+- **训练数据集:** `codeparrot/codeparrot-clean`

+## 使用方法
 
-### Model Sources [optional]
+### 快速开始
 
-<!-- Provide the basic links for the model. -->
+```python
+from transformers import AutoTokenizer
 
-- **Repository:** [More Information Needed]
-- **Paper [optional]:** [More Information Needed]
-- **Demo [optional]:** [More Information Needed]
+# 加载分词器
+tokenizer = AutoTokenizer.from_pretrained("your-username/code-search-net-tokenizer")
 
-## Uses
+# 对Python代码进行分词
+code = """
+def hello_world():
+    print("Hello, World!")
+    return True
+"""
 
-<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
+tokens = tokenizer.encode(code)
+print(f"Token IDs: {tokens}")
 
-### Direct Use
+# 解码回原文
+decoded = tokenizer.decode(tokens)
+print(f"Decoded: {decoded}")
+```
 
-<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->
+### 主要特性
 
-[More Information Needed]
+- 优化了对 Python 关键字的处理（def, class, import 等）
+- 更好地处理缩进和代码格式
+- 支持 Python 特有的语法结构
+- 减少了对代码的过度分词
 
-### Downstream Use [optional]
+## 技术细节
 
-<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->
