Data Analysis with Polars and Python
Welcome to the most comprehensive Polars course on Udemy!
Data Analysis with Polars and Python offers 22+ hours of in-depth video tutorials on the powerful Polars data analysis library. The course also includes a wide collection of datasets, quizzes, and coding challenges to aid your learning.
Why Polars?
The core of Polars is written in Rust, one of the fastest programming languages in the world. At the same time, the library enables us to write our code in Python, the most popular language in the world. We gain the best of both worlds -- the speed and efficiency of Rust and the simplicity and elegance of Python.
Who is this Course For?
The course is designed for learners of all skill levels, from experienced data analysts to students who have never programmed before. Lessons include:
installing Python and Polars on your computer
understanding the core mechanics of Python
working with the Jupyter Lab coding environment
Whether you've spent time in a spreadsheet software like Microsoft Excel/Google Sheets or another data analysis library like Pandas, Polars can help take your data analysis skills to the next level.
What Topics Will We Cover?
We'll cover the core objects of Polars including:
Series
DataFrames
LazyFrames
Most of our work will focus on the DataFrame, a 2-dimensional table of rows and columns. We'll cover data manipulation operations including:
sorting
filtering
grouping
aggregating
de-duplicating
pivoting
deleting
joining
replacing
working with text data
working with temporal/datetime data
We'll also cover some of Polar's unique column data types including:
lists
arrays
structs
and more!
Data Analysis with Polars and Python
I'm excited to share everything I've learned about Polars, a powerful library that is quickly emerging as a dominant competitor in Python's data science ecosystem. I look forward to seeing you in the course!
