In Python, comment is used to add explanatory notes or remarks within the code. It helps other developers or yourself to understand the code better. Comments are ignored by the interpreter and do not affect the execution of the program.

Here’s an example of a comment in Python:

python # This is a comment

On the other hand, pip is a package manager for Python that allows you to install, upgrade, and manage Python packages. It simplifies the process of installing external libraries or modules that are not included in the Python standard library.

To install a package using pip, you can use the following command in the terminal:

pip install package_name

For example, to install the requests package, you would run:

pip install requests

pip also provides other functionalities like upgrading packages, uninstalling packages, and listing installed packages.
