Without functions: by repeatedly writing the code to draw a triangle with. With a Python function call: by generating lots of coordinates and feeding them to your “draw triangle” function.

In Python, the mere act of making a function call incurs a relatively large amount of overhead. If some function is called repeatedly in a tight loop, even if it isn’t a long-running function ...

Example implementation involves defining a Python function, binding it to the LLM, and testing execution. LangGraph is used for creating agents that perform complex tasks autonomously.
