How do I install a .whl file? I have the Wheel library but I don't know how to use it to install those files. I have the .whl file but I don't know how to run it. Please help.

You normally use a tool like pip to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.
For this to work, you do need to install the wheel package:
pip install wheel
You can then tell pip to install the project (and it'll download the wheel if available), or the wheel file directly:
pip install project_name # discover, download and install
pip install wheel_file.whl # directly install the wheel
The wheel module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:
python -m wheel install wheel_file.whl
Also see the wheel project documentation.

If you already have a wheel file (.whl) on your pc, then just go with the following code:
cd ../user
pip install file.whl
If you want to download a file from web, and then install it, go with the following in command line:
pip install package_name
or, if you have the url:
pip install http//websiteurl.com/filename.whl
This will for sure install the required file.
Note: I had to type pip2 instead of pip while using Python 2.
