Windows:
Go To official Website (https://www.python.org/downloads/) & download python
Python 3.6.4 *** or Python 2.7.14. While installing tick option - Add Python 3.7 to PATH.
After, installing Python, you can install Jupyter Notebook to create notebook, to store python scripts and to run directly on network devices.
Installation of Jupyter can be done by PIP. PIP is already installed in Python.
To Upgrade PIP Command - pyhon -m pip install --upgrade pip
Command on Windows CMD: python -m pip install jupyter
To Launch Jupyter – Command on Windows CMD: jupyter notebook. It will open browser with IP - http://localhost:8888/tree
Linux:
apt-get update
apt-get install python -y
apt-get install build-essential libssl-dev libffi-dev -y
apt-get install python-pip -y
pip install cryptography
pip install --upgrade pip
pip install paramiko
pip install netmiko
GNS3 Appliance:
Network Automation - This Tool runs in GNS3VM as Docker container which has in build Ubuntu as base with python2 & Python 3 installed. Other installed tools are Netmiko, Pyntc, NAPALM and Ansible
By Default – No IPv6 address is configured. To get Ipv4 address from DHCP address below are the steps
Step1: edit file /etc/network/interfaces by command – nano /etc/network/interfaces
Step2: uncomment last 2 lines – ‘auto eth0’ & ‘iface inet dhcp’ . Then save file.
Step3: Stop & Start again ‘Network Automation’ and see ipv4 address by command - ifconfig

Ansible, Netmiko, Paramiko, NAPALM & PYNTC
Installation of these libraries can be done on Ubuntu/Windows client running Python.
GNS3 Appliance – Network Automation has pre-installed Paramiko, Netmiko & Ansible
Paramiko – Used for implementation of SSHv2 protocol providing basic server & client functionality
Netmiko is great Python network library for SSH and Telnet network access too many vendor network OS’s including Cisco IOS, Juniper JunOS and Arista EOS and many more.
Ansible: Ansible is an open source IT configuration management (CM) and automation platform, provided by Red Hat. It uses human-readable YAML templates so that users can program repetitive tasks to occur automatically, without learning an advanced language.
NAPALM (Network Automation and Programmability Abstraction Layer with Multivendor support) is a Python library that implements a set of functions to interact with different router vendor devices using a unified API.
NAPALM and pyntc make it easy to configure and interact with network devices using an API such as NETCONF or using SSH. Don’t reinvent the wheel. Use the tools available to you to quickly and easily automate your networks.
