When a package is created, which of the following file it containsAinit.pyB__init__.pyC_init_.pyDinitSebelumnyaBerikutnya

The correct answer is:

B) __init__.py

Explanation:

In Python, when you create a package (which is essentially a namespace for a collection of related modules), it typically requires an __init__.py file. This file is used to mark the directory as a package and is executed when the package or a module in the package is imported.

1. The __init__.py file can be empty, but it can also execute initialization code for the package.
2. The presence of the __init__.py file is a way for Python to differentiate between a regular directory and a package. Note that in Python 3.3 and later, it is possible to have a directory be considered a package without an __init__.py file, but it’s still a common practice to include it for clarity and compatibility with older versions.
3. The alternatives presented, init.py, _init_.py, and init, do not follow the naming convention or function of the package init file in Python.

In summary, to define a package properly in Python, you should include the __init__.py file.
