Strengths:

• The solution correctly implements the queue using two stacks.
• The time and space complexity are optimal.
• The code is readable and well-structured.

Areas for Improvement:

• Follow Python naming conventions for variables (e.g., in_stack instead of instack).
• Consider using more descriptive method names (e.g., is_empty instead of empty).
• The empty method can be simplified to return the boolean expression directly (e.g., return len(self.instack) == 0 and len(self.outstack) == 0).
