Python not wait for sub Function

[DavinE]

Hello Guys,

I have a problem with my function...
i hope anyone can help my out.

this is my sample code:

def generatePDF(self, data, customer, customer_project, materiallistType):
        Querry = []
        Querry.append(['Herstellerbeschreibung', 'Herstellernummer', 'Lieferantennummer', 'Anzahl', 'Preis', 'Kommentar'])
        Querry.extend(data)
        
        filePath = self.setFileNamePDF(customer, customer_project, materiallistType)
        # while filePath is None:
            # pass
        print("Bin hier FEHLER ???")
        print(filePath)
        sys.exit(1)

my Problem here is that print(filePath) is None....
but i did not understand why...

when i try something like that in an Test.py it works but not here.... does anyone know why ?

@DavinE There are two base threads in Pythonista and you can force to run a process in The main_thread or in tHe ui one.
Remove this line and it is still not ok, put the line @on_main_thread

[DavinE]

@cvp like this:

@on_main_thread
def generatePDF(...)

and here:

def setFileNamePDF(self, customer, customer_project, materiallistType)

nothing ?

@DavinE Sincerely, I don't know but personally I would put the @on_main_thread before the other def.

@cvp okay thanks i try it and response to you xD

Hi everyone,

Is it possible to launch a python command without waiting for a return ? and therefore start the next command without waiting the previous one to finish ?

I searched and asked also on StackOverflow but so far I didn't found what I was looking for...

something that look promising might be the
1
concurrent.futures import ThreadPoolExecutor, ProcessPoolExecutor
as seen here -> https://stackoverflow.com/a/60832288/11943028

But this example is focus on results that I don't need. any ideas ?

Thank you.

@montykit,

in my case @ui.in_backgroundworks... and don't wait for a return

maybe for you too

[cvp]

@montykit see the threading module, you could start one thread for each command

But what do you call a command?

[cvp]

@montykit try

import threading

class MyThread(threading.Thread):
    def __init__(self,cmd):
        threading.Thread.__init__(self)
        self.run = cmd

def cmd1(): 
    s = 0
    for i in range(1000):
        s += 1
    print(s)
    
def cmd2(): 
    s = 0
    for i in range(1000):
        s += i
    print(s)


MyThread(cmd1).start()
MyThread(cmd2).start()
