How to use Python for Data Analysis

Data is considered the new oil in this digital era. This statement illustrates how all modern IT systems are powered by gathering, storing, and reviewing data for different needs. It is about business decisions, weather forecasting, biology research, or a marketing strategy concept. The multidisciplinary methodology to both of these scenarios is focused on statistical models, statistics, graphs, databases, and the logic of business or science underlying data analysis. Therefore we need a programming language that can satisfy all these complex data science needs. Python is bright because it has many libraries and features that make data science requirements easy to meet.

What is Data Science?

Let us start the journey to learn Data Science with Python by a first understanding of data science. Data science is all about discovering and analyzing real-world data and using it to solve industry problems.

Python – Know more

Originally, Python was a general language. However, this language has been devoted to analyzing data and predictive modeling over the years, with broad community support.

Python’s good thing is that it is open-source, and installation is simple. It is also possible to get rid of the local installation in the cloud and function with Python. Python is a world-class programming language that lets you better manage your data for several purposes.

We live in high technology, advanced computers, and mobile solutions in the modern age. Data is a critical element of any organization and company. The data flow must be obtained, stored, analyzed, and done as efficiently and precisely as possible. The amount of data nowadays can be extensive, making it time-consuming and expensive information handling. Because of this, the data science field is increasingly growing and generating new vacancies and opportunities.

Why learn Python for data analysis?

Python is a multiparadigm programming language: the coding world’s Swiss Army knife. It supports, among other items, object-oriented programming, structured programming, and feature patterns. 

As a preference of language for data processing, Python recently acquired much interest. Here are some reasons to help to learn Python.

  • Open source – install free of charge. 
  • Wonderful online community
  • Easy to analyze 
  • Can be a popular data science language and development of web-based analytics products

Data Science with Python – Course details

Learn to analyze data using Python. This course leads you to discover several different kinds of data from the core of Python. You can learn how to generate analytical data, conduct fundamental statistical analysis, construct insightful visualizations of data, forecast future data trends, and more!

You’re going to learn how: 

  • Data sets to import 
  • Clean and organize data for analysis.
  • Managing DataFrame pandas 
  • Data summary 
  • Build ML models with Scikit-learn 
  • Create data pipelines
  • Data analysis with Python is carried out by seminars, practice on laboratories, and assignments.


You should have a basic knowledge of writing code in Python, using some Python IDE, or running Python programs before continuing with this tutorial.


First of all, the essential things on which we have to concentrate before knowing Python is. 

  • Learn the fundamentals of Python 
  • Learn Python Libraries that are useful for machine learning, data science, and data analysis. 
  • Try to practice Python Data Analysis projects. 
  • Innovative technology applications

As with many other programming languages, Python’s popularity has been due to the libraries available: about 72,000 are contained in and continuously increasing inside Python Package Index (PyPI).

How to use Python?

Data loading 

The first step is to load the data into your program. You can achieve it by using Python Pandas library’s (read_csv).

Data Cleanup 

The next move is to investigate data anomalies with data analysis. This step also involves evaluating the null values and to replace them with other values or to drop them entirely.


After cleaning is finished, we can step on and imagine the relationship between our dataset’s different aspects.

How to launch your career in Data Science?

For professionals in the Data Analytics industry, Python is a must-learn ability. As the IT industry rises, the demand for trained data scientists is booming, and Python has developed into the most common programming language for data-driven growth.

The lack of expertise in data science gives an excellent opportunity to someone who wants to enter a hot area of the job market. When companies employ data scientists, they respect activities with Python in particular. With its emphasis on data science and machine learning, the course program is an excellent way to develop your skills.

If you want to speed up your career, graduate, or learn for your own sake, many ed-tech providers offer courses for you.

In the data science field, there are several different positions. A Data visualization expert, Data engineer, Machine learning expert, data scientist are some of the various roles you might perform. It will be better to take on one task than another, depending on your background and work experience.

What can you learn from the course?

  • Contain Python’s basic language and how it relates to data science. 
  • You can practice Data Science using Jupyter notebooks on IBM Cloud 
  • Analyze Python-based data, such as Pandas and NumPy. 
  • Build awesome matplotlib, folium, seaborne data visualizations. 
  • Able to build Machine Learning models with Scipy and Scikit-learn. 
  • Explore abilities to tackle real-life data science issues.

Wrapping up

Your success depends directly on your ability to draw information and insights from data to make successful strategic decisions and remain competitive and advanced. Data Science with Python is the globally acclaimed programming language to properly treat the data for different reasons.

You can also try out a free Python course and then move over to learn Data science applications.

Python is an excellent tool for data scientists and is becoming increasingly popular. It is easy to learn because it fits well with other databases and resources such as Spark and Hadoop. Mostly it has a high level of computation and efficient libraries for analytical data.
