Python

General Information

Administration of Python environments.

Checklist

• Distro(s): Enterprise Linux 6/7

• To avoid breaking system packages(ie yum uses python), let system packaged python versions stay maintained by the official repos.
• Use EPEL/software collections along with something such as virtualenv to maintain development environments.

Software Collections allow for environments such as newer Python versions to be installed via repos and not conflict with the default system version.

See Software Collections Instructions
