Overview
Introducing Python and Web Services Protocols for Network Engineers 3.0 is a 4-day hands-on course that focuses on the interoperability of Python programming with Networking to prepare the Next Generation Engineers for Software Defined Networking. This class is designed for Network Engineers and Administrators looking to add necessary programming skills in preparation for various ACI and SDN technologies as well as interacting with WEB Services on appliances such as the F5, A10, and Cisco UCS. The course has been modified to emphasize the skillset of data extraction for interacting with BIG DATA platforms.

This ability includes being able to meet these objectives:
Describe and execute dictionaries
Delete dictionaries
Describe and execute dictionaries with lists
Describe and execute Regular expressions (match, search, findall, sub)
Module 2 - Lesson 1: Introduction to Web Services Protocols
This lesson will detail the basic Web Services Protocols used throughout the course. The RESTful API and Management Information Model are introduced as an extension of the common CLI over SSH method for accessing data.
This ability includes being able to meet these objectives:
Describe the common Web Services Protocols and Transport methods
Describe The Management Information Tree view of accessing objects
Describe Object naming conventions
Describe what an encoded document is in relation to plain text.
Module 2 - Lesson 2: XML and JSON
This lesson will detail the properties and formatting of an encoded documents as a means of accessing displaying data. This is a prerequisite to understanding how information is manipulated or extracted from an appliance that offers a web based service.
This ability includes being able to meet these objectives:
Describe basic XML concepts
Describe the format of an XML document
Describe basic JSON concepts
Describe the format of a JSON document
Module 2 - Lesson 3: Data Models
This lesson introduces XML as the common data model upon which many platforms utilize today. Although these models are evolving into models such as YANG, it is not a primary focus of the course as extraction is the goal no matter what the model is.
This ability includes being able to meet these objectives:
Describe the generic parts of an XML Schema
Describe the flow of how an XML Schema is used
Module 2 - Lesson 4: Modifying the Schema
This lesson introduces the various ways to modify and read objects that are contained within a schema.
This ability includes being able to meet these objectives:
Use CURL to post and retrieve data from a schema
Use POSTMAN to post and retrieve data from a schema
Use Python with a native API to an appliance
Use Python without a native API to an appliance
Module 2 - Lesson 5: Data Extraction and Manipulation
This lesson teaches the use of taking extracted formatted documents and parsing them for data. Network Engineers gain the benefit of being able to provide data scientists with the data necessary to use the data in a meaningful way.
This ability includes being able to meet these objectives:
Load and parse a JSON Document
Load and Parse an XML Document
