Is there a way to find out, which variable was most recently defined within the global namespace?
Preferably a general python solution, but otherwise a solution that works within jupyter notebook would be acceptable as well. (I know about receiving cell_output using _, but the defined variable was not printed)
Since Python 3.7, the dictionaries keep the order of the inserted keys. So, the last declared variable should be the last entry in globals().
