The raw data available in the world is massive. To make sense of these available statistics, data analysis comes into the picture. All organizations are trying their level best to traverse every opportunity that comes their way, in order to emerge victorious. To understand data analytics with Python, we must first know what data analytics is and what a data analyst actually does.
What is Data Analysis?
Data Analytics begins by gathering all the possible raw data at a tedious pace, cleaning it, and making it ready for further analysis. This is where languages related to programming like Python and PI Data Tools flourish. A Data Analyst takes all the raw and complex information and makes something useful out of it by interpreting these insights so that the company can make the most out of this information. Data Analytics with Python saves a lot of time.
Application of Data Analytics With Python
The sky is the limit on this in today’s world as the amount of data available is infinite across all kinds of businesses and organizations globally. To make better and faster business decisions, reduce overall business costs, and develop innovative and user-friendly products, Data Analytics with Python is used.
Armed with all the essential data after the removal of the unnecessary ones, companies are then able to function well by making better decisions for their audience, thereby being one of the reliant industries in which they work.
Types of Data Analysis
1. Descriptive Analysis- Instigates What has occurred?
Usually, a beginner is assigned with this work in the Data Analysis domain, showcasing what’s going on in the business and setting the foundation of the information relating to business. For instance, studying the total number of cosmetics sold, growth of sales, and the profit made in the past few years.
2. Diagnostic Analysis- Instigates Why it has occurred?
This analysis investigates and finds the main cause of the problem. For instance, why was there a sudden deterioration or dip in sales or why did the company’s profit go down or is the product relevant to the current trend and so on? This is where one creates the sales outlook and is considered to be one step ahead of descriptive analysis.
3. Predictive Analysis- Instigates What will occur?
The predictive analysis predicts what the company should do in the future for growth. The total units that would sell, the profit that the company can expect in the near future based on the growing trends. This analysis is important as businesses are trying to make themselves aware of the planning they need to execute to excel in their respective industries.
4. Prescriptive Analysis- Instigates How to make it occur?
Prescriptive analysis, the most advanced stage of analytics, is a combination of all the above three mentioned analyses. This stage also involves advice on what do to next. For instance, whether to launch a new product at a favorable time or make a particular investment or decision.

This is interesting because Python, Java, C, and .NET have huge collections of libraries and they are always competing with one another. But Python is an open source, one can always have easy access to those libraries which otherwise wouldn’t have been available for free.
Some of the Popular Libraries in Python Are Listed Below:
Its full form is numerical in python. NumPy is a model which is an alternate format lab. It is used to create multi-dimensional arrays, and calculate the matrix and it has way too many predefined mathematical functions.
The pandas library has powerful functionalities in order to process the data as it provides us with more data structures to play with. Its full form is the Python data analysis library. As the name suggests, it’s mainly used for Data Analysis. With the help of pandas, one can create a multi-dimensional structured data set.
It also helps one do some kind of processing and manipulation for the data. Similarly, data can be read from any source like a text file, a database, a CSV, PST, or JSON. Once read it, you can pass it on and convert it into a data frame so that it can be in the format of 2D.
Once we are done with the data analysis, it’s time to move ahead and visualize the data and it’s done by the most popular library of python- Matplotlib. It provides a wide variety through which one can plot the data through line graphs, bar graphs, scatter plots, pie-charts, histograms, and many more.
In order to use the Seaborn library, you first need to install it either through the installation of anaconda or type Pip Install Seaborn into your command line. After the installation, you’ll need to import that library in whichever python script you are working on. Most people use the Jupyter Notebook.
Another amazing feature of seaborn is that it interacts easily with other libraries like Matplotlib and Pandas. Seaborn can group the data, aggregate it and plot it all from the Pandas dataframe. There are many plots that can be constructed with the help of Seaborn like KDEplot, pairplot, violinplot, boxplot, distplot, and swarmplot.
Scikit-learn is vital for a python programmer, learning machine-building skills. This library simplifies the complex problems relating to machine building. In Python, Scikit-learn is known as the father of programming as it is the core library. It’s impossible for programmers to implement machine learning without the usage of Scikit-learn.
