Reading a book about Python, the author shows a command in which you can create an Egg and upload of your package at PyPi (official python package repository). Basically using the command below:
python setup.py bdist_egg upload --identity="Jon Snow" --sign --quiet
I did not really understand exactly what this "Egg" would look like. Was it just a module? What is Python Egg? How can it actually be used?
The .egg file is a distribution format for Python packages. It's just an alternative to a source code or Windows exe distribution. But note that for pure Python, the .egg file is completely cross-platform.
The .egg file itself is essentially a .zip file. If you change the extension to "zip", you can see that it will have folders inside the file.
