Introduction
Congratulations on purchasing Python Data Science and thank you for doing so.
The following chapters will discuss all of the steps that we need to know when it comes to working with data science along with the Python language. There are a lot of great parts that come with using Python on your data science project, and when we are able to combine these two topics, it becomes so much easier to handle our data, form a good analysis with it, and see some of the results that we want in the process. This guidebook is going to explain how we are able to get all of this done.
This guidebook will start off by taking a look at what data science is all about. There are a lot of companies throughout many industries that are already working with data science because they see the enormous value that they are able to receive from this kind of process. We will take a look at some of the steps that come with the data science lifecycle and how companies are able to benefit from implementing it for themselves.
From here, we are going to move on and take a look at what the Python coding language is all about. Python is just one of the languages that we can work with on data science, but because of the ease of use, and all of the great libraries and extensions that we are able to use with it, we can find that this is one of the best. We will take some time in this guidebook to look through what Python is about and how to download it on different operating systems, the basics of coding in Python, and the data types that work with the Python language.
Once we have taken some time to look through this information and see how we can make this work for our own needs, we are going to move on to look in more depth about how data science is able to provide us with some of the benefits that we need. We will look more at the process of data analysis, the importance of working with data visualization and so much more. And when we get to the end, we will even look at a practical example of how you can work with data science in a real-life example to make things work for your needs.
There is so much that we are able to do when it comes to working with data science and all of the information that comes in our data. Moreover, with the help of the Python coding language, we are able to learn how to make the right models and more to make all of this come together. When we are ready to learn more about Python data science and what it is able to do for us, make sure to check out this guidebook to get started.
With so many books made for this very subject, we are so happy you chose this one! We promise we made this book with the intention of making sure all information is as useful as enjoyable as much as we can. Happy reading!
Chapter 1: The Basics of Data Science
Data science is a role that is taking up a lot of space for many businesses. There is a wealth of information out there that they are able to use for their own advantage, but they just need to know where to gather it, and how to analyze all of that data for their own needs. Sometimes, this is going to be a process that takes a lot of time and effort and can be hard to keep up with and ensure that we are doing it in the right manner.
Data science is the process of gathering, organizing and cleaning, analyzing, and then visualizing data so that we can use that information to make smart business decisions. It is becoming more and more important to a lot of businesses, and it is likely that this will take over as one of the main forms of making big decisions in the future. With that in mind, lets take some time to look more in-depth at data science and how businesses are using it for their own needs.
Why Is Data Science So Important?
The first thing that we need to take a look at here is the idea of why data science is so important and helpful for our needs. In a traditional manner, and in the past, the data that businesses were supplied with would be structured and smaller in size. This would make it so much easier to go through the data and see what was there, and often the business intelligence tools were all that was needed to see what was available and what business decisions needed to be made.
However, the data that we are able to take a look at today is so much different. Unlike the traditional data systems, which was mostly structured, it is common for the data that companies collect today to be unstructured, or at the very least, semi-structured. This is going to make it more difficult to sort through and understand, and that is why the process of data science has expanded into what it is today.
The unstructured data that companies are collecting today is going to be produced from distinctive sources like text files, financial logs, multimedia forms, devices, and sensors. The straightforward business intelligence tools that were so popular in the past are not able to handle the job, and businesses are turning to more complex and advanced kinds of tools and algorithms to get some of the analysis done and to help with getting all of the meaningful information and insights out of that data.
But this is not the only reason why businesses are finding the process of data science to be so popular and helpful to what they are doing. Data science is able to help the company recognizes the definite requirements of their customers based on the actual data that is out there. Data science is able to help us handle some things like predictive analysis to figure out what is the most likely outcome of a decision. And it can help us figure out how to make the right decisions that will push our business into the future and beat out all of the competition that is out there.
