Module vs. Package vs. Library in Python

In Python, the terms "library," "module," and "package" are often used interchangeably, but they do have specific meanings:

1. "Module":
   - A single file of Python code.
   - Can be imported and used in other Python scripts.
   - Example: "math.py" that contains mathematical functions.

2. "Package":
   - A collection of Python modules grouped together.
   - Includes an "__init__.py" file to signify it's a package.
   - Can be a single-level (a directory with modules) or multi-level (a directory with subdirectories of modules).
   - Example: "numpy", which includes multiple modules for various numerical operations.

3. "Library":
   - A collection of modules and packages bundled together to provide specific functionalities.
   - More general term, often used to describe a collection of related modules and packages.
   - Example: "tqdm" and "colorama" are libraries that provide progress bars and colorized text output, respectively.

So, while "tqdm" and "colorama" are libraries, they are also packages because they contain multiple modules. It's just that "library" is a higher-level term that often describes a set of packages and modules that provide certain functionalities.
