# Debugging Ansible ## Interactively Debugging with Ansible's Python Version Usually with: `/opt/ansible-2.9.17/bin/python` (adjusted for whichever version of Ansible you're using). ## Cleaner Output For cleaner output when debugging Ansible playbooks, use ```code [defaults] ... stdout_callback = yaml ``` (`debug` and `json` are also available) It takes output from looking like this: ``` fatal: [localhost]: FAILED! => { "changed": false, "module_stderr": "/opt/ansible-2.9.17/local/lib/python2.7/site-packages/OpenSSL/crypto.py:12: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team.
