    "Azure Container Apps dynamic sessions provides a secure and scalable way to run a Python code interpreter in Hyper-V isolated sandboxes. This allows your agents to run potentially untrusted code in a secure environment. The code interpreter environment includes many popular Python packages, such as NumPy, pandas, and scikit-learn.\n",
