A Wrapper class is used to organize codes after creating classes with wrapper logic to organize instances that are created later in the program. Next, create class Wrapper and two functions i.e __init__ and get_name. If the class uses containers of ROS messages, an extra conversion step must be added. Wrapper Methods in Python There are two popular libraries in Python which can be used to perform wrapper style feature selection — Sequential Feature Selector from mlxtend and Recursive Feature Elimination from Scikit-learn. First, we create one function which is named as a wrapper Example. Python wrapper allows users to write only python code, even when calling non python libraries.Decorators are also called 'wrappers'.
