Yes, LangChain supports multi-turn conversations with prescribed call-script functionality for interactive coding assistants.
Here is the code snippet you can refer to:

In the above code, we are using the following key approaches:
- Memory Management: Stores conversation context for smooth multi-turn interactions.
 
- Customizable Call-Scripts: Enables structured dialogues for coding assistance.
 
- Integration with APIs: Supports tools like OpenAI, Anthropic, and local models.
 
- Chain & Agent Support: Allows for dynamic and reactive workflows.
 
- Prompt Engineering: Enhances interactions with structured templates.
 
Hence, LangChain is an effective framework for building structured, multi-turn coding assistants with prescribed dialogue flows.
