Why Python for Data Science?
The programming requirements of data science demand a very versatile yet flexible language that is simple to write code but can handle highly complex mathematical processing. Python is the most suited programming language for such requirements as it has already established itself both as a language for general computing as well as scientific computing. Most importantly it is a free and open-source and the most powerful programming language, so free Python is considered the most preferred language for Data Science.
Moreover, it is being continuously upgraded in the form of a new addition to its plethora of libraries aimed at different programming requirements. Below we will discuss such features of python which makes it the preferred language for data science.
- It is simple and easy to learn, we can achieve results in fewer lines of code.
- Its simplicity also makes it robust to handle complex scenarios with minimal code and much less confusion on the general flow of the program.
- It supports cross-platform, thus the same code works with multiple environments.
- It executes faster than other similar languages used for data analysis like R and MATLAB.
- Its excellent memory management capability, especially garbage collection makes it versatile in gracefully managing a very large volume of data transformation.
- Python has got a very large collection of libraries and packages, which serve as special-purpose analysis tools where we can directly use code from other languages (Java or C).
About the free Python for Data Science course
This free Python for data science course is a part of the Data Science MicroMasters program, will introduce you to a collection of powerful, open-source, tools needed to analyze data and to conduct data science. Specifically, you’ll learn how to use:
- Jupyter notebooks
- Sci-kit Learn
- NLTK (Natural Language Toolkit)
and many other tools.
In this free python for data science course, you will learn the above tools all within the context of solving compelling data science problems.
After completing this free python course, you’ll be able to find answers within large datasets by using python tools to import data, explore it, analyze it, learn from it, visualize it, and ultimately generate easily sharable reports.
By learning these skills, you’ll also become a member of a worldwide community that seeks to build data science tools, explore public datasets, and discuss evidence-based findings. Last but not least, this course will provide you with the foundation you need to succeed in later courses in the Data Science MicroMasters program.
What you’ll learn from this free Python for Data Science course?
- The basic process of data science
- Python and Jupyter notebooks
- An applied understanding of how to manipulate and analyze uncurated datasets
- Basic statistical analysis and machine learning methods
- How to effectively visualize results
By the end of this free python course, you should be able to find a dataset, formulate a research question, use the tools and techniques of this course to explore the answer to that question, and share your findings.
Even though this is a free Python course, as it is an advanced-level course, a learner is required to have knowledge/experience on the following:
- Previous experience with any programming language (Java, C, Pascal, Fortran, C++, Python, PHP, etc.) is expected.
- This includes a high school, or undergraduate equivalent, to an introduction to computer science course.
- Learners should be comfortable with loops, if/else, and variables.
Syllabus for the free Python for Data Science course
There are different modules in this free python course, broken down into 10 weeks. The beginning of the course is heavily focused on learning the basic tools of data science, while the latter half of the course is a combination of working on large projects and introductions to advanced data analysis techniques.
- Welcome and overview of the course.
- Introduction to the data science process and the value of learning data science.
- In this optional week, we provide a brief background in python or Unix to get you up and running.
- If you are already familiar with python and/or Unix, feel free to skip this content.
Jupyter and Numpy
- Jupyter notebooks are one of the most commonly used tools in data science as they allow you to combine your research notes with the code for the analysis.
- After getting started in Jupyter, we’ll learn how to use NumPy for data analysis.
- NumPy offers many useful functions for processing data as well as data structures that are time and space-efficient.
- Pandas, built on top of NumPy, adds data frames that offer critical data analysis functionality and features.
- When working with large datasets, you often need to visualize your data to gain a better understanding of it.
- Also, when you reach conclusions about the data, you’ll often wish to use visualizations to present your results.
- With the tools of Jupyter notebooks, NumPy, pandas, and Visualization, you’re ready to do sophisticated analysis on your own.
- You’ll pick a dataset we’ve worked with already and perform an analysis for this first project.
- To take your data analysis skills one step further, we’ll introduce you to the basics of machine learning and how to use sci-kit learn – a powerful library for machine learning.
Working with Text and Databases
- You’ll find yourself often working with text data or data from databases.
- This week will give you the skills to access that data.
- For text data, we’ll also give you a preview of how to analyze text data using ideas from the field of Natural Language Processing and how to apply those ideas using the Natural Language Processing Toolkit (NLTK) library.
Week 9 and 10
Final Project for the free Python for Data Science course
- These weeks let you showcase all your new skills in an end-to-end data analysis project.
- You’ll pick the dataset, do the data munging, ask the research questions, visualize the data, draw conclusions, and present your results.
