What is the purpose of the __init__.py file in a Python package?
a) To define a function
b) To initialize a variable
c) To indicate that the directory is a Python package
d) To import built-in functions
Answer:
c) To indicate that the directory is a Python package
Explanation:
The __init__.py
file is used to indicate that a directory is a Python package. This file can be empty or contain initialization code that runs when the package is imported. It also allows you to control what is imported when a package is imported using the from package import *
syntax.
# Example __init__.py
from .module1 import some_function
from .module2 import another_function
In this example, the __init__.py
file is used to import specific functions from the modules in the package, making them directly accessible when the package is imported.
The __init__.py
file is an important part of Python’s packaging system, allowing you to define the structure and behavior of your packages.
