## Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("KpRT/qwen-python-finetuned")
tokenizer = AutoTokenizer.from_pretrained("KpRT/qwen-python-finetuned")

prompt = "Write a function to reverse a string"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=256)
code = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(code)
```
