We generally use one-hot encoding to solve the disadvantage of label encoding. The strategy is to convert each category into a column and assign it a 1 or 0 value. It is a process of creating dummy variables. Let’s see how we can implement it inPython: Import pandasaspd#Creating a da...
While the import statements in the first cell probably look familiar from your experience of using python in the command line or in a script, the%matplotlibinline command is not actually python: it is a markup instruction to the notebook thatmatplotlibimages are to be displayed inline the brows...

Categorical data is a type of data that represents categories or labels rather than numerical values.
In the relational plot tutorial we saw how to use different visual representations to show the relationship between multiple variables in a dataset. In the examples, we focused on cases where the main relationship was between two numerical variables. If one of the main variables is “categorical”...
As with many other aspects of the Data Science world, there is no single answer on how to approach this problem. Each approach has trade-offs and has potential impact on the outcome of the analysis. Fortunately, the python tools of pandas and scikit-learn provide several approaches that can...
