Self_correcting_coding_agent
1.0.0
该存储库实现了一个 LLM 代理，用于接收用户的提示和相应的单元测试。代理生成代码，测试其正确执行，并确保其通过单元测试。如果代码无法执行或任何单元测试失败，代理将重新生成代码，直到成功。
该项目基于LangChain的Notebook（https://github.com/mistralai/cookbook/blob/main/third_party/langchain/langgraph_code_assistant_mistral.ipynb）中的代码构建，其中代理根据用户的提示生成代码并检查是否执行作品。
该项目的主要贡献是将单元测试集成到代码执行过程中。
此外，原始的 Jupyter Notebook 代码已被重构为适合部署的结构化 Python 项目。通过遵循最佳编码实践，代码已经模块化，创建了可重用的功能，并确保了适当的文档和测试。结果是一个组织良好的 .py 项目，可维护且可用于生产。
git clone https : // github . com / paulomuraroferreira / Self_correcting_coding_agent . git
cd Self_correcting_coding_agent$ pip install - e .创建.env文件并填写以下环境变量：
OPENAI_API_KEY = your_openai_api_key
OPENAI_CHAT_MODEL = "gpt-4o-2024-08-06"在main.py文件中输入代码的提示符。提示应该是描述性的并指定类的名称。
例如：
QUESTION3 = '''
Python Class Description
Class Name: BankAccount
Description:
The BankAccount class represents a user's bank account, allowing for deposits, withdrawals, and viewing the transaction history. The class ensures that withdrawals cannot exceed the current balance and that deposits and withdrawals are properly recorded in the transaction history.
Attributes:
balance (float): The current balance of the account, initialized to 0.
transactions (list): A list to store the history of transactions. Each transaction is stored as a dictionary with keys type (either 'deposit' or 'withdrawal'), amount, and date.
Methods:
deposit(amount: float) -> None: Adds the specified amount to the balance and records the transaction.
withdraw(amount: float) -> bool: Attempts to subtract the specified amount from the balance. Returns True if successful, otherwise returns False. Records the transaction if successful.
get_balance() -> float: Returns the current balance.
get_transaction_history() -> list: Returns a list of all transactions.
'''
main = Main(QUESTION3)
将单元测试代码添加到 src/unit_test_folder 中的 .py 文件中。另外，从 code_solution.py 文件中导入相应的类。例如，对于上面的提示，LLM会生成一个名为BankAccount的类。因此，src/unit_test_folder/test_unit_test.py 应包括：
从 src.code_solution 导入银行帐户
运行 main.py 文件。
python main . py 对于上面的示例，代码将显示以下输出：

Here is my attempt to solve the problem: The BankAccount class is designed to manage a user's bank account by allowing deposits, withdrawals, and tracking transaction history. It ensures that withdrawals do not exceed the available balance and records each transaction with details such as type, amount, and date.
Imports: from datetime import datetime
Code: class BankAccount:
def __init__(self):
self.balance = 0.0
self.transactions = []
def deposit(self, amount: float) -> None:
self.balance += amount
transaction = {

'amount': amount,
'date': datetime.now()
}
self.transactions.append(transaction)
def withdraw(self, amount: float) -> bool:
if amount > self.balance:
return False
self.balance -= amount
transaction = {

return True

================================== Ai Message ==================================
Here is my attempt to solve the problem: The previous solution did not handle cases where negative amounts were deposited or withdrawn. The unit tests expect a ValueError to be raised in such cases, but the original implementation did not include this validation. To fix this, we need to add checks in the deposit and withdraw methods to raise a ValueError if the amount is negative.
Imports: from datetime import datetime
Code: class BankAccount:
def __init__(self):
self.balance = 0.0
self.transactions = []
def deposit(self, amount: float) -> None:
if amount < 0:
raise ValueError("Deposit amount must be positive.")
self.balance += amount
transaction = {
'type': 'deposit',
'amount': amount,
'date': datetime.now()
}
self.transactions.append(transaction)
def withdraw(self, amount: float) -> bool:
if amount < 0:
raise ValueError("Withdrawal amount must be positive.")
if amount > self.balance:
return False
self.balance -= amount
transaction = {
'type': 'withdrawal',
'amount': amount,
'date': datetime.now()
}
self.transactions.append(transaction)
return True
def get_balance(self) -> float:
return self.balance
