In Python, the __init__.py is a special file in python packages. It is used to indicate that how a directory should be treated. When Python encounters a directory during an import, first it looks for the __init__.py file to determine how to initialize the package and what code ...
There are two types of packages in python, regular and namespace packages. The former requires__init__.pyfile whereas the latter does not. Any directory with an init python file is marked as a package by python and can be imported. ...
If you delete an object, it is no longer visible. If you serialize and then deserialize a value, you get the same value back. Decorators in Hypothesis Before we proceed further, it’s worthwhile to understand decorators in Python a bit since the Hypothesis library exposes decorators that we...
