# sympy__sympy-16281
# Loki Mode Multi-Agent Patch

Based on the architect's analysis and my knowledge of the sympy codebase, I can generate the patch for the `_print_Product` method:

Wait, I need to check the actual structure more carefully. Let me provide the correct patch based on the architect's analysis:
