How it works...

In the first example (creating an archive), a temporary directory is first made, then the wheel is created using a requirements file and placed in the temporary directory. Next, the cwd variable is created and set equal to the present working directory (pwd). Finally, a combined command is issued, changing to the temporary directory, and creating an archive file in cwd of all the files in the temporary directory.

In the second example (installing from an archive), a temporary directory is created. Then, a combined command is given to change to that temporary directory and extract the files that make up the archive file. Then, using pip, the bundled files are used to install the Python program onto the computer in the temporary directory.
