fix/issue-325361846/"No-module-name-board"
master
This is needed because in Python 3.x open("directory/file", "a") doesn't create the needed directory and tinydb needs this directory for the file data/data.json (see game.py, line 119).
Replaced xrange with range.
For this, xrange was replaced by range and for imports of the own library lib.x was used instead of x.
