How to practice data analysis python
Looking to start a data science career? Just as in any new field, you’ll need a lot of practice. Let’s explore where you can find data science projects to practice your newly acquired Python skills. Show Organizations large and small all over the world use Python in their software development and data science projects. But even if you are very excited about a career in data science, it can seem very challenging to learn a new programming language. So you may wonder whether Python is worth learning and how difficult it is to learn a programming language like Python. In fact, Python is very beginner-friendly; you can learn it pretty fast, especially with enough practice. In this article, I’ll guide you through several resources for practicing Python coding skills with real-world projects. But first, let’s start with some basic definitions. What Is Data Science?Data science combines programming, math, statistics, and business expertise to extract meaningful insights from data. Basically, data scientists are given business problems to be solved. They apply their understanding of industry and business processes, statistical and machine learning tools, and Python to solve the problems. Data scientists work along with data engineers and data analysts to assist businesses with data-driven decisions. However, their roles are different:
Data science is a career of the future and Python is one of its key tools. Big tech companies, small startups, research organizations, and even academia choose Python because of its simplicity, rich ecosystem, large and supportive community, efficiency, and scalability. If you are new to programming but excited to learn coding with Python, I recommend trying our Python Basics mini-track. Its three interactive courses have 200+ coding challenges. Once you are familiar with the basics, you can continue your learning journey with your first data science project. How to Start Your First Data Science ProjectFor your first project, it’s a good idea to choose a topic that you’re interested in – it’s a great source of motivation. So think about what you’d find fun to work on: football statistics, climate change visualization, forecasting cryptocurrency prices, etc. You can find more data science project ideas here. For example, let’s say you want to explore crime statistics in your city so you can choose the safest neighborhood to buy a house. You can consider lots of different factors, including the number of murders, robberies, car thefts, and other crimes per 1,000 people; the number of policemen per 1,000 people; average household income, etc. Here are just a few examples of what you can do using the data science toolkit:
Python can assist with all these tasks, including time series forecasting, exploratory data analysis, building machine learning models, visualizing data, and more. Data science and Python are really powerful together. However, you need to practice Python a lot to become an effective data scientist. Writing code for different scenarios and testing your skills with various projects and challenges is the shortest path to getting expertise in data science. So, let’s see where you can find real-world data science projects. Where to Find Datasets and Sample Data ProjectsThere are numerous resources that offer real-world datasets to practice newly acquired Python and data science skills. Here are a few options:
It’s Time to Practice Python!Hopefully, you’ll find your perfect dataset for your next data science project somewhere on the above list. However, if you feel you need to refresh and/or consolidate your Python skills – or if you’re like me and prefer to learn Python with fun, easy-to-follow interactive online courses – you might want to start with one of the following learning tracks:
The constant (and long-term) demand for data scientists shows how popular this field is. Today’s companies and organizations prefer to make data-driven decisions, and they need data scientists for this. So, do your best to learn and practice Python for data science. Very soon, you'll have a successful and well-paid career as a data scientist. Thanks for reading, and happy learning! How do you practice Python data analysis?How to Learn Python for Data Science.
