Now, class objects are also callable objects.

If the instance attribute list doesn’t have that attribute, Python continues looking up the attribute in the class attribute list. in_features. The feature class or feature layer that will be converted. Feature Layer. out_path. The location where the output feature class will be created. This can be either a geodatabase or a folder. If the output location is a folder, the output will be a shapefile. Workspace;Feature Dataset.

Classes — Python 3.7.17 documentation. 9. Classes ¶. Classes provide a means of bundling data and functionality together.

Sep 11, 2023 · Object-oriented programming (OOP) is a method of structuring a program by bundling related properties and behaviors into individual objects. In this tutorial, you’ll learn the basics of object-oriented programming in Python. Conceptually, objects are like the components of a system. Think of a program as a factory assembly line of sorts. To define a class attribute, you place it outside of the __init__() method. Use class_name.class_attribute or object_name.class_attribute to access the value of the class_attribute. Use class attributes for storing class contants, track data across all instances, and setting default values for all instances of the class.
