Python ako spravne pouzivat threading?

[Wangarad]

Zdravim.
Snazim sa spravne pouzivat threading spojeny s GUI. Mam ale pocit ze nieco je zle.
Idea je taka ze nastartujem thready potom sa nastartuje GUI a to nasledne skusa ci je thread aktivny ak nie tak ho znova nastartuje. Ale mam pocit ze nieco je zle resp. slo by to vyriesit elegantnejsie. Vie niekto poradit ako sa to ma "spravne" riesit?

layout = [[sg.Output(size=(80,10))],

window = sg.Window('Shifter V 1.0', layout)

#XML_domino.XML_To_DB(Model, Batch)

S1t = threading.Thread(target=Stage_1, args=("task",))
S1t.start()
S2t = threading.Thread(target=Stage_2, args=("task",))

Co je Stage_1,Stage_2, Stage_2? Co to ma cele delat?

[Wangarad]

To su funkcie ktore sa v podstate vykonavaju v cykle a obsluhuju databazu v style (select/update) etc skrz pyodbc

[IDontCare]

Jeste je tam zahadna funkce check(), nehlede na to ze pokud je splinena podminka  if(SQL_Status == True and RFID_Status == True) bude se cyklus provadet do nekonecna, pouziti vlaken nedava moc vyznam. Dalsi vec je, ze pokud Stag_1, Stage_2, Stage_3 maji byt provedeny v poradi, coz naznacuje jejich nazev je pouziti vlaken vubec vhodne?

[Wangarad]

IDontCare: praveze nie tie stage si predstav ako nezavysle. Teda kazda moze v kazdom momente dostat data. Preto su oddelene.
check() - je len funkcia bokom.
Cela idea je je sa nastartuje GUI. Spravy si spojenia a potom len v klude checkuje ci thread nespadol.

Ide mi o to ci je toto korektne riesenie.

Jestli je to nový projekt, nebylo by lepší použít async?
