Python 3.7 kernel conflicting with random.py files

Reproduziere den Fehler, indem du einen Jupyter-Notebook-Server in einem Verzeichnis mit einer leeren random.py startest. Untersuche anschließend den Startpfad rund um ipykernel_launcher.py und den in der Traceback-Ausgabe gezeigten Import von tempfile.py. Als erledigt gilt die Aufgabe, wenn der Python 3-Kernel startet und verfügbar bleibt, ohne die lokale random.py zu importieren; im Issue ist kein Zieltest genannt.

Copied over from https://github.com/jupyter/notebook/issues/5470, since this is most likely an ipykernel and not an notebook issue:

When running a jupyter notebook with python 3 kernel from a notebook server started in a directory that contains a file random.py (file must only exist in the same directory, can be empty), the kernel seemingly tries importing from this file in the process:

[I 16:26:31.107 NotebookApp] Kernel started: 2dde5ce2-6742-4523-bbea-1e82edd3f963

where (...) is my user. The server tries to restart the kernel till it hits the limit of 5 tries via the KernelRestarter always resulting in the error above and the kernel dies after that.

Updating does not seem to resolve the problem.
