Machine learning models require all input and output variables to be numeric.
This means that if your data contains categorical data, you must encode it to numbers before you can fit and evaluate a model. One of the ways to convert categorical variables to numeric variables is the use of pandas get_dummies method.
When using the dummies method, we should be careful not to run into the dummy variable trap. Dummy variable trap causes multicollinearity, a situation where independent variables are highly correlated leading to inaccurate results.
This tutorial demonstrates the use of pd.get_dummies method and how to manage the dummy variable trap in a few lines of code.
