Pandas pipe function can help us chain together functions that takes either dataframe or series as input. In this introductory tutorial, we will learn how to use Pandas pipe method to simplify code for data analysis. We start with a dataframe as input and do a series of analysis such that that each step takes… Continue reading Pandas pipe function in Pandas: performing PCA

How to Change Matplotlib Plot’s Style
In this post we will learn how to find all available style options for matplotlib plot themes and learn to set a style for matplotlib plot. To illustrate the styling options available in Matplotlib, we will use histogram made from beta distributions. To get started, let us load the modules needed. We can use style… Continue reading How to Change Matplotlib Plot’s Style
How to Select Columns/Rows by substring match in Pandas
In this post, we will learn how to select columns of a Pandas dataframe or a rows of a dataframe based on substring match in Pandas. We will use Pandas filter() function with argument “like” to select columns/rows, whose names partially match with a string of interest. Let us load the necessary modules. We are… Continue reading How to Select Columns/Rows by substring match in Pandas
Barplots and Countplot with Seaborn’s catplot
Love it or hate it, barplots are often useful in a quick exploratory data analysis to understand the variables in a dataset. In this post, we will see multiple examples on how to make barplots/countplot using Seaborn’s catplot() function. A couple of years ago Seaborn introduced catplot() function that provides a common framework to make… Continue reading Barplots and Countplot with Seaborn’s catplot
How to Change the Order of Columns in a Pandas Dataframe
In this tutorial, we will learn how to change the order of columns in Pandas dataframe. We can change the order of the columns in multiple. Here, we will see two ways to change the order of the columns. First, let us load Pandas. We will use gapminder dataset to change the column orders. Let… Continue reading How to Change the Order of Columns in a Pandas Dataframe
