Pyrhon 3 file sharing variable


Pyrhon 3 file sharing variable



I want to import a var from another python file.



This first file runs on the side of file2 on a second window.



File1.py


def onlinecheckext():
global onlinecheckvarr
while 1:
try:
onlinecheckscc = pyautogui.locateOnScreen(imPath("start_detect.png"))
if onlinecheckscc is None:
logging.debug("I am Online")
onlinecheckvarr = True
time.sleep(2)
else:
logging.debug("I am not online")
onlinecheckvarr = False
time.sleep(2)


except:
logging.debug("Online check fail")
return False



File2.py


from file1 import onlinecheckvarr
while onlinecheckvarr is True:
print("TEST")
else:
print("Test2")



Error : NameError: name 'onlinecheckvarr' is not defined.



I have try almost everything and still didn't get it, it's a global var and i imported it right i think but it still throws errors.





First of all: Did you call onlinecheckext() before the invokation of File2.py? Otherwise onlinecheckvarr is not yet defined yet

onlinecheckext()


onlinecheckvarr





file1.py runs independet in another window, its only genrating values for file2.py, but its not working right i think, the thoughts behind it is that file1.py checks the stuff and if file1.py fails file2.py can jump to another state.

I'd guess, you missunderstood the effect of a global variable. "global" does not mean, that you can grap the variable from "anywhere on your computer", it's only global within the script and is absolutely capsuled from other processes. For your purpose you need to place the variable/values somewhere "public", where both processes can read from (e.g. write to a file), which is not so good, though. A very good solution would be, to have the processes communicate via a socket. Btw: a python file does not do anything, it's the interpreter that executes.

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".
