Configure Python with iPython, Jupyter and MySQL on Ubuntu 18.10

If you’re thinking of learning Python, you may be struggling with where and how to start. It could be a pretty hard question before you know why you want to learn Python because Python, as a popular programming language, is used in many fields and industries such as

  . web development (create web applications on a server)
  . software development (work with software developing tools to create work flows)
  . mathematics (scientific computing, data analysis, data visualization)
  . system scripting
 
As I am asked the question by a university student and Python is wildly used for data analysis/visualization in university, I going to demonstrate how to qhickly build a Python data analysis/visualization developing environment on Ubuntu 18.10.
