Course Overview

Data Science with Python is an online course taught by Udacity. It is a course that prepares you for a career as a data scientist.

You are going to learn how to use:

Let me briefly explain why each of these skills is so important.

Python

Python is one of the most in-demand languages to date. It is really popular among data scientists.

Python is a language that is easy to get started with. It sometimes reads like English.

Python is a go-to language when it comes to data science and analysis.

With Python, you collect, clean, operate, analyze, and visualize data.

SQL

SQL is used to communicate with a database that holds data related to your program. SQL is a language that is used to perform tasks, such as update/retrieve database data.

When dealing with data, it is important to be able to store the data for easy access. This is why SQL is also taught in this course.

Command Line

Command-line is a text-based interface to a computer. You can use a command-line to write instructions to the computer. The command line then executes these instructions right away.

You can use the command line for so many things. However, when it comes to data science, the command line is useful for:

  • Version control (Git)
  • Running Python programs
  • File management

Git

Git is the most popular version control system for your programming projects.

Learning how to use Git (and Github) is inevitable if you want to build a career as a data scientist. This is because Git makes it possible for teams to work on the same project simultaneously.

Instead of copy-pasting your changes in code and sending them to your colleagues, you merge the changes to the codebase from your branch.

Git stores the history of your projects. If you want to reset your piece of code to where it was 3 months ago, no problem.

Anyway, it is important to learn Git sooner or later.

It is awesome that this course teaches you how to use Git!

Course Highlights

  • Learn how to perform SQL queries.
  • Understand Python programming basics.
  • Use popular Python libraries to operate on data.
  • Get real-life experience with the hands-on projects.
