In this tutorial, you’ll learn how to change font sizes on a Matplotlib plot. You’ll learn everything you need to know to customize your Matplotlib plot to have exactly the font sizes you want. Data visualization is an incredible tool
In this tutorial, you’ll learn how to define and set the marker size in Matplotlib scatterplots. Being able to control the size of your Matplotlib scatterplots allows you to add extra information to your scatterplots. This allows you to communicate
In this tutorial, you’ll learn how to create pair plots in Seaborn, using the sns.pairplot() function. These visualizations plot pairwise relationships in a dataset so that each variable in a dataset will be plotted against each other variable in the
In this post, you’ll learn the difference between arrays and lists in Python. Both these data structures let you store data in Python and share many similar properties. However, they also let you do quite different things and knowing when
In this tutorial, you’ll learn how to use Pandas to count unique values. You’ll learn how to count unique values in a column, in multiple columns, and in an entire DataFrame. Being able to count unique values can have important
In this tutorial, you’ll learn the differences between Python lists and tuples. Lists and tuples are fundamental Python container data structures. On the surface, they seem very similar. However, there are a number of unique differences between them that makes
The median absolute deviation (MAD), is a robust statistic of variability that measures the spread of a dataset. In this tutorial, you’ll learn how to use Python to calculate the median absolute deviation. By the end of this tutorial, you’ll
In this tutorial, you’ll learn how to change the plot and figure sizes in Matplotlib. Data visualization is a valuable tool to help you communicate your data. Being able to customize exactly how your plots are sized gives you the
In this tutorial, you’ll learn how to get and check the type of a Python object using the type() and isinstance() functions. Everything in Python is an object and knowing what the object’s type is allows you to make better-informed
In this tutorial, you’ll learn how to use Python to write (or save) to a text file. Python provides incredible opportunity to read and work with text files – being able to save the output to a text file is
In this tutorial, you’ll learn how to use Python to check if a list empty. Python lists are one of the most versatile and widely-used container objects. Because Python lists are iterable, you may often want to first check if
In this tutorial, you’ll learn how to use Python to create a directory if it doesn’t exist. Creating directories programmatically can save you a ton of time. However, not checking if the directory exists first can lead to significant problems,
