This program (gdd.py) repeatedly shows you random German noun phrase elements to be inflected properly to the specified grammatical case (NOM = Nominative, ACC = Acusative, DAT = Dative, GEN = Genitive) and number (SG = Singular, PL = Plural), and then waits for you to find the correct declension, and then (after you click Enter) shows you the answer. Entering q and then Enter ends the loop and the program terminates.
This program can be used to memorize the correct declensions of German determiners, adjectives and nouns.
The lists of determiners, adjectives and nouns used by the program are hard-coded in the gdd.py script. You can add new vocabulary items to those lists if you desire so.
You need Python 3 to run this program.
