Python For Data Analysis

Data is an essential part of any enterprise or business. It is critical to collect, process, and analyze data flow in a timely and accurate manner to discover information useful for decision making in business.

The data science industry is rapidly expanding. Data volume can be large, making information handling difficult and time-consuming. Python is a popular programming language in scientific computing, because it has many data-oriented feature packages that can speed up and simplify data processing, thus saving time.

What is Python?

Python is an object-oriented, high-level programming language. Its built-in data structures and properties, combined with dynamic typing (meaning we don’t have to declare the type of variable like in C or Java) and binding, make it ideal for application development and its use as a scripting language. Python’s simple syntax emphasizes readability and reduces programming maintenance. Python is a programming language that can be used for a wide range of tasks such as software creation, web development, script writing, unlike HTML, CSS, and JavaScript. Python, one of the most popular programming languages in the world, has created everything from Netflix’s recommendation algorithm to the software that controls self-driving cars. Python is a general-purpose language, which means it’s designed to be used in a range of applications, including data science, software and web development, automation, and generally getting stuff done.

Why is Python Essential for Data Analysis?

  • It’s Flexible: If you want to try something creative that’s never done before; then Python is perfect for you. It’s ideal for developers who want to script applications and websites.

  • It’s Easy to Learn: Thanks to Python’s focus on simplicity and readability, it boasts a gradual and relatively low learning curve. This ease of learning makes Python an ideal tool for beginning programmers. Python offers programmers the advantage of using fewer lines of code to accomplish tasks than one needs when using older languages. In other words, you spend more time playing with it and less time dealing with code.

  • It’s Open Source: Python is open-source, which means it’s free and uses a community-based model for development. Python is designed to run on Windows and Linux environments. Also, it can easily be ported to multiple platforms. There are many open-source Python libraries such as Data manipulation, Data Visualization, Statistics, Mathematics, Machine Learning, and Natural Language Processing, to name just a few (though see below for more about this).

  • Huge libraries collection : It has many completely free libraries that are open to the public. That is a key factor that makes Python essential for data analysis and in data science as well.

What is Python used for?

Clearly, Python is a popular and in-demand skill to learn. But what is python programming used for? Python can be used for:

1. AI and machine learning

Because Python is such a stable, flexible, and simple programming language, it’s perfect for various machine learning (ML) and artificial intelligence (AI) projects. In fact, Python is among the favourite languages among data scientists, and there are many Python machine learning and AI libraries and packages available.

2. Data analytics

Much like AI and machine learning, data analytics is another rapidly developing field that utilises Python programming. At a time when we’re creating more data than ever before, there is a need for those who can collect, manipulate and organise the information.

3. Data visualisation

Data visualisation is another popular and developing area of interest. Again, it plays into many of the strengths of Python. As well as its flexibility and the fact it’s open-source, Python provides a variety of graphing libraries with all kinds of features.

4. Programming applications

You can program all kinds of applications using Python. The general-purpose language can be used to read and create file directories, create GUIs and APIs, and more. Whether it’s blockchain applications, audio and video apps, or machine learning applications, you can build them all with Python.

5. Web development

Python is a great choice for web development. This is largely due to the fact that there are many Python web development frameworks to choose from, such as Django, Pyramid, and Flask. These frameworks have been used to create sites and services such as Spotify, Reddit and Mozilla.

6. Game development

Although far from an industry-standard in game development, Python does have its uses in the industry. It’s possible to create simple games using the programming language, which means it can be a useful tool for quickly developing a prototype. Similarly, certain functions (such as dialogue tree creation) are possible in Python.

7. Language development

The simple and elegant design of Python and its syntax means that it has inspired the creation of new programming languages. Languages such as Cobra, CoffeeScript, and Go all use a similar syntax to Python.

8. Finance

Python is increasingly being utilised in the world of finance, often in areas such as quantitative and qualitative analysis. It can be a valuable tool in determining asset price trends and predictions, as well as in automating workflows across different data sources.


Python is a valuable part of the data analyst’s toolbox, as it’s tailor-made for carrying out repetitive tasks and data manipulation, and anyone who has worked with large amounts of data knows just how often repetition enters into it. By having a tool that handles the grunt work, the data analysts are free to handle the more interesting and rewarding parts of the job.
