Use functions or APIs from external libraries to develop a computer program : Creating a Package

The video tutorial explains how to create and use Python packages. It starts by defining a package as a collection of modules, typically organized in folders. The tutorial then demonstrates creating a package by setting up a folder with an __init__.py file and adding Python files. It shows how to import and use functions from these files. The tutorial also covers creating subfolders, using constants, and understanding dot notation for imports. The video emphasizes the organization and structure of Python packages, making it easier to manage and use code across different projects.

What is a Python package primarily composed of?

• A database of Python functions

• A set of compiled binaries

• A single Python file

• A collection of modules or Python files

What is the purpose of the __init__.py file in a package?

• To execute the package

• To indicate the folder is a package

• To store package metadata

• To compile the package

Why might a developer include the file name at the top of a Python file?

• To ensure the file runs correctly

• To help identify the file in text editors

• To increase execution speed

• To comply with Python syntax rules

How can you import a function from a package in Python?

• Using the 'import' statement

• Using the 'load' keyword

• By copying the function code

• By creating a symbolic link

What is the purpose of using uppercase for variable names in Python?

• To indicate a constant

• To mark a global variable

• To denote a private variable

• To highlight a deprecated feature

What does the dot notation in Python imports signify?

• A hierarchical structure of packages

• A method call

• A comment

• A file path

How can you simplify long import paths in Python?

• By creating a symbolic link

• By using the 'shorten' keyword

• By using an alias

• By renaming the package
