How to Learn Python for Data Science?

Data scientists are in demand across various fields like finance, fashion, healthcare, etc. According to the U.S. Bureau of Labor Statistics, data scientist positions will continue to be among the fastest-growing jobs in 2024. The projected increase in job openings from 2022 to 2032 is 35%. Python was explicitly mentioned in 78% of data scientist job offers in 2023 and 57% in 2024 src-365datascience. Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Data Scientists widely use Python.

Python has in-built mathematical libraries and functions which makes it easier to calculate mathematical problems and to perform data analysis.

Python is an open-source platform, thereby it has a simple syntax and is easy to learn which consequently makes it a great language for beginners learning data science. Python has several powerful libraries that make data analysis and visualization easy. Also, python is platform-independent since it allows developers to run the code on Windows, Mac OS X, UNIX, and Linux. Nowadays, Python is the most famous coding language for data science. One of the most important strengths of Python in data science is its rich set of libraries for data analysis and visualization. For instance, Pandas is a powerful data manipulation library that provides data structures and functions for efficiently handling structured data, including filtering, aggregation, and merging operations.

There are a lot of career opportunities in this field including data scientist, data analyst, database administrator, analytics manager, etc. With immense career opportunities in this field, data science has become the most attractive job profile in the past few years. In this blog, we will learn about the importance of Python for data science and how to become one. We will explore the available IT training centers for learning Python for data science. We will also explore TechAxis the leading IT training institute in Nepal and how this IT training center will help you to lead your career.

Learning Python for Data Science: A Step-by-Step Guide

Here in this section let’s discuss some of the basic guide that helps you to learn Python from scratch.

Learn Python fundamentals

The first step to begin your journey of data science is to learn Python programming basics. You can easily learn Python fundamentals by joining online classes or practicing through YouTube videos. You can also go for data science boot camps. To get expertise in Python fundamentals, you need to stay consistent and practice as much as you can. You should have covered these topics in the Python fundamentals.

  • Variables, Data Types, Operators
  • Control Flow (if/else statements, loops)
  •  Functions (defining and using functions)

Dive into Data Structures

Organizing, managing, and storing data is crucial as it enables easier access and efficient improvisations. The important Python data structures in Python include lists, sets, tuples, and dictionaries. Each of the data structures is unique in its way. Data Structures help you to organize your data in such a way that allows you to store collections of data, relate them, and perform operations on them accordingly. It is one of the fundamental concepts that beginners get to know about when learning the Python course.

  • Python data structure- Lists: A list in Python is defined as an ordered collection of data that allows easy use for a set of data. While creating a project in Python, it is the most essential data structure. The term “ordered collection” signifies that each value in the list comes with an order that uniquely identifies them.
    For instance: List A=[item1, item2, item3, …item n]

  • Python data structure- Tuples: Tuples are one of the data structures and it is a collection that is ordered and immutable. Compared to lists, tuples use less memory, and they make program execution faster.
    For example: some_tuple=(item1, item2, item3, …item n)

  • Python data structure- Dictionaries: Dictionaries in Python data structure enable users to easily write efficient code. Since its keys are hashable, it is also known as a hash table in many languages.
    For example:print(hash(“b”))

Master Essential Libraries

Libraries are the most important part of Python learning. You should master them thoroughly.

Libraries are pre-written codes and functions that we can use in specific programs for specific operations. There are lots of libraries in Python. Among them, NumPy, Pandas, and Matplotib are the most important ones.

  • NumPy — NumPy, is one of the most broadly-used open-source Python libraries and is mainly used for scientific computation and array manipulation; it is also the foundation for many features of the pandas library.
  • Pandas — A Python library created specifically to facilitate working with data which includes data analysis, data manipulation, and data cleaning. This is the support of a lot of Python data science work.
  • Matplotlib — A Python visualization library that creates quick interactive, animated charts from your data. It is free and open source.

NumPy and Pandas are great for exploring and playing with data. Matplotlib is a data visualization library that makes graphs as you’d find in Excel or Google Sheets.

Practice Makes Perfect

After completing your Python course, practice is all you need. There are a lot of online data science communities that will help you achieve your goals like Kaggle, DataCamp, etc. These online coding platforms are free. In these platforms, you get to showcase your way of solving a specific problem and simultaneously compete with the others. You can also build your projects and experiment with it. They provide hundreds and thousands of coding challenges specially designed for users which tests your Python skills. To become an aspiring data scientist, you need to have a portfolio. Your portfolio should include all of your projects that showcase your Python skills. Lastly, improve your Python skills. After being adept in these basic Python skills and creating your portfolios, you should move on to advanced Python learning like machine learning. Applying advanced data science techniques will help you to stand out of the crowd and also enhance your portfolio.
