Getting Started with Data Science

In this complete tutorial, you will complete the course of Data Science. Data Science is all about using data to solve problems. Many people have a doubt why is data science so important? It is important as the fundamental goal of data science is to help companies to take quick and smarter decisions that help them to be the top of their market. As per the analysis, the number of companies using data science is increasing. So, start this to become a Data Scientist.

What will you learn in the complete course?

Python
Numpy
Pandas
Matplotlib
Seaborn
Data Visualization
Geographical Plotting
Machine Learning Intro
Linear Regression
Logistic Regression
K Nearest Neighbors
Decision Trees
Much More.

So, In this tutorial let’s start with Python.

The reason why python is one of the most powerful languages and why Python is more popular is because of its hundreds of add on libraries that help in data manipulation in data science, machine learning, and much more. There are many ways to download python on your computer system, but the best way is to download full ANACONDA installation. Python is much more than just a python standard library. ANACONDA is one of the most powerful tools to perform data manipulation techniques for different usage. Here to master in PANDAS, we will be jupyter notebook to learn and practice the things. Jupyter notebook is a part of anaconda library. There is a very good thing about this tool, which is an open platform for individuals to work on and explore.

Other tools in ANACONDA

Jupyterlab
Jupyter Notebook (This would be used in all the tutorials)
Powershell prompt
Pycharm
Qt Console
Spyder
Glueviz
Orange 3
RStudio

How to download ANACONDA

To dowload ANACONDA on your system, follow the steps:

Click here to open “Anaconda.com” – Open.
Now, go to the Products > Individual Edition.
Click on the Download and it’s a bit big file (466MB) so it takes time for completion of the download.
Once the installation is done, we shall move to the next step in learning the pandas library.
The next step you need to do is opening a Jupyter Notebook.
Open ANACONDA Navigator in your system.
Next launch Jupyter Notebook

Open the Jupyter Notebook, the dashboard would look as shown below:

The files represented in the above picture are your recent files that you have worked in jupyter notebook. These files are stored in a cloud storage. 4. Open an empty file to write down our first python for data science and machine learning Code.

Once you click on the Python 3, the screen will be as shown below.

Red part- The cell – where you need to write the python code.
Green part- output or errors of the program ar
The black arrow shows “LOGOUT”, by clicking which you can exit from the jupyter notebook.

Important Tips for Beginners

Click on Untitled text to change the file name that you are working in
Next, click on the first tool in Redbox to save the file ( although mostly everything will save automatically )
Click on file, to open a new notebook, to copy the notebook, rename, and few basic changes.
The place enclosed within the blue box is known as a CELL, where we write our code.
Click on Edit option, copy the cells, move and remove the cells, and make few changes to the notebook cells.
To run and execute a code click the “RUN” option on the top or simply press “ SHIFT + ENTER” keys on your keyboard.

Conclusion

I hope you understood clearly how to download ANACONDA and a bit about Jupyter Notebook is covered. Please feel free to ask doubts in the comment box below. You will learn the Basics of Python and Python for Data Science in the next tutorial.
