Define your function example as this:- def exemple(func_name): def dostuff1(): print(‘Stuff 1’) def dostuff2(): print(‘Stuff 2’) def dostuff3(): print(‘Stuff 3’) func_dic = { “dostuff1” : dostuff1, “dostuff2” : dostuff2, “dostuff3” : dostuff3 } return func_dic[func_name] Then call your function in the other function like this: def training(): exemple(“dostuff2”)() I hope it helps! 3 solved Python … Read more
If the rest of the code is correct, this should do: def add_sighting(session, spawn_id, pokemon): obj = Sighting( pokemon_id=pokemon[‘id’], spawn_id=spawn_id, expire_timestamp=pokemon[‘disappear_time’], normalized_timestamp=normalize_timestamp(pokemon[‘disappear_time’]), lat=pokemon[‘lat’], lon=pokemon[‘lng’], ) # Check if there isn’t the same entry already existing = session.query(Sighting) \ .filter(Sighting.pokemon_id == obj.pokemon_id) \ .filter(Sighting.spawn_id == obj.spawn_id) \ .filter(Sighting.expire_timestamp > obj.expire_timestamp – 10) \ .filter(Sighting.expire_timestamp < obj.expire_timestamp … Read more
The condition is tested before each iteration of the loop, not after every statement inside the loop body. So even though queue.pop(0) empties the list, you still execute the next statement and print the message. Then it goes back to the beginning and tests queue again. This time the condition fails and the loop terminates. … Read more
