Paramiko is a Python implementation of the SSHv2 protocol. Just like the pxssh subclass of Pexpect, Paramiko simplifies the SSHv2 interaction with the remote device. Unlike pxssh, Paramiko is only focused on SSHv2 and provides both client and server operations.

Paramiko is the low-level SSH client behind the high-level automation framework Ansible for its network modules. We will cover Ansible in the later chapters, so first, let's take a look at the Paramiko library.
