Conventions

Throughout these tutorials, we use the following conventions:

• All code examples use the from pyqpanda3 import core import style
• Code blocks include descriptive comments above each example
• Mathematical formulas use LaTeX notation: inline $...$ and block-level $$...$$
• Diagrams use Mermaid syntax for flowcharts and sequence diagrams
