A colleague asks you to share it. You zip the folder and email it. They unzip it, run <code>python main.py</code>, and get <code>ModuleNotFoundError</code> because they do not have the dependencies. Then they install the dependencies, but the wrong versions. Then they have Python 3.8 and your f-string walrus operators do not parse.</p> <p>Proper packaging eliminates all of this.
