Intelligent code generation program for data processing

For data processing needs such as CSV/Excel, the following process can be realized:

  1. Tool Preparation: Install data processing libraries such as pandas as dependencies
  2. Customization Tools: Use @tool to create data processing functions such as:
    @tool
    def read_csv(path).
    """Read CSV file tool""""
    return pd.read_csv(path)
  3. security sandbox: Configure a standalone Python environment to execute the generated code
  4. Examples of tasks::
    "Analyze sales.csv and calculate sales averages by month"
    Intelligent bodies are automatically generated:
    df = read_csv('sales.csv')
    print(df.groupby('month')['sales'].mean())

Advanced Tips:

  • Combining multiple tools to realize ETL processes
  • Monitoring Big Data Processing Progress with .stream()
  • Configure sandbox network isolation for sensitive data
