API and API Design with Python (GK100417)

Kurskode GK100417 Kategori Underkatergori

Learn to design, build, and interact with APIs using Python.
Application Programming Interfaces (APIs) have become increasingly important as they provide developers with connectivity to everything from rich datasets in an array of formats (such as JSON) to exposing the configurability of software applications and network appliances. Lessons and labs focus on using Python to interact, design, and build APIs for the purposes of scripting automated solutions to complex tasks. Class is a combination of live demonstrations and hands-on labs.

COURSE OBJECTIVE:
• Client-side Python Scripting to RESTful (and non-RESTful) APIs
• Design RESTful API interfaces with Flask Web Framework
• Overview of Django
• Deploy your Python web apps as Docker containers
• Open SSH sessions and pass commands to remote servers
• Move files via SFTP
• Parse and manipulate popular data structures (JSON, CSV, Excel, and YAML) as pandas dataframes
• Best practice techniques

TARGET AUDIENCE:
System Administrators
Network Engineers
Software Developers
Python Enthusiasts
