Questions
Question
Write Python 3.12 code only.
Define exactly one function named prime_factors(n).
Return a list of prime factors in ascending order, with repetition.
Raise TypeError if n is not an int.
Raise ValueError if n <= 1.
Do not use any imports (no numpy, requests, or other libraries).
Sandbox note: dunder attribute access is blocked (for example, type(x).__name__). Avoid names/attributes starting with '__'.
Expected output format:
- Return exactly one fenced Markdown code block starting with ```python and ending with ```.
- Put only valid Python code inside that block (no prose before/after).
- Use 4 spaces for indentation (not tabs).
- Do not return JSON and do not wrap code in a "function" key.
Sample input/output behavior:
- prime_factors(36) -> [2, 2, 3, 3]
Task:
Write a Python 3.12 function for prime factorization.
