Seit 2002 Diskussionen rund um die Programmiersprache Python
https://www.python-forum.de/
Es gibt noch zwei dinge die ich generell anmerken muss, da ich sie wahrscheinlich nicht ausreichend ausgedrückt habe:BlackJack hat geschrieben:Die API ist eine Katastrophe
was meinst du mit Dateitests? die ganzen if-statementsBlackJack hat geschrieben:die ganzen Dateitests sind Mist
der code ist nur ale kleiner teil eines grösseren Programms gemeint. wenn man nur den code benutzt um mit diner datei zu interfacen, dann gibt es keine multiline statements.BlackJack hat geschrieben:JSON kann auch mehr als eine Zeile enthalten, auch wenn *Du* das jetzt nicht so schreibst (an welcher Stelle ist das eigentlich garantiert?)
da habe ich mich vertippt.BlackJack hat geschrieben:und natürlich nutzt Du ``+`` um Zeichenketten zusammenzusetzen.
und ich bin jetzt auch schon davon weg.Code: Alles auswählen

most of the def's are created for a list with following format:

createFile(path, filename) creates a file with name FILENAME at PATH
read(filePath) returns the read out text from file PATH must be valid json
write(filePath, data) writes DATA in the file PATH must be valid json
