Hi team Good day The problem I meet when I add "aLOCK = threading.RLock()" to PositionB, the program will report error "name 'aLOCK' is not defined ", but when I change this code to PositionA, it can run normally, is there any difference for the code between 'if __name__ == "__main__:"', can you help me, thanks! The file I was attached, please change the extend ".pyx" to ".py", thanks, code as below, tried python2.7 and python3.4: import threading import time from multiprocessing import Process #PositionA aLOCK = threading.RLock() def Save_runnedCMD(filename, strings): aLOCK.acquire() with open(filename, "at") as f: f.write(str(strings) + "\n\r") aLOCK.release() def runCMD(filename): time.sleep(1) cmd = "testtest" Save_runnedCMD(filename, cmd) def Thr_run(filename): t = [] for i in range(2): tt = threading.Thread(target = runCMD, args=(filename,)) tt.start() t.append(tt) for tt in t: tt.join() if __name__ == "__main__": filename = "./testaaaaa.log" #PositionB #aLOCK = threading.RLock() while 1: t1 = Process(target=Thr_run, args=(filename, )) t1.start() t1.join() Error info as below: D:\Appppp>python testa.py Exception in thread Thread-1: Traceback (most recent call last): File "C:\Python34\lib\threading.py", line 921, in _bootstrap_inner self.run() File "C:\Python34\lib\threading.py", line 869, in run self._target(*self._args, **self._kwargs) File "D:\Appppp\testa.py", line 15, in runCMD Save_runnedCMD(filename, cmd) File "D:\Appppp\testa.py", line 7, in Save_runnedCMD aLOCK.acquire() NameError: name 'aLOCK' is not defined Exception in thread Thread-2: Traceback (most recent call last): File "C:\Python34\lib\threading.py", line 921, in _bootstrap_inner self.run() File "C:\Python34\lib\threading.py", line 869, in run self._target(*self._args, **self._kwargs) File "D:\Appppp\testa.py", line 15, in runCMD Save_runnedCMD(filename, cmd) File "D:\Appppp\testa.py", line 7, in Save_runnedCMD aLOCK.acquire() NameError: name 'aLOCK' is not defined

change spacing to two instead of four with pep8 or flake8?
by Dennis June 29, 2019

June 29, 2019

Hi, In Pylint you can change the spacing multiplier from 4 spaces to two in its pylintrc, but for the life of me I cannot find a way to do this with the flake8 / pep8 utilities. I want to avoid ignoring E111 altogether if at all possible, because it may catch other spacing problems that are not as obvious. hacky/non-hacky solutions welcome of course. If this is too specific and I should go to the pep8/flake8 MLs that is welcome advice too. Thanks, Dennis

Same with me, except that I tried to install Python 3.6.3. Unchecking "Install launcher for all users" helped, however.

embedding python - PyImport_ImportModule returns null
by jkpangtang＠yahoo.com March 28, 2019

March 28, 2019

I am trying to embed python within a c program, but I can't get PyImport_ImportModule() command to load my module. Please let me know what I'm doing wrong. -- #file func.py def func1(): print "inside func1()" -- //main.c int main() { PyObject *pFunc, *pModule; Py_Initialize(); pModule=PyImport_ImportModule("func"); //fileread.py if(pModule==NULL) { PyErr_Print(); fprintf(stderr,"Failed to load \"%s\"\n","func"); } //etc.... } --- Both main.c and func.py are in the same directory. I run main and get the error Failed to load "func", meaning that PyImport_ImportModule returns NULL. What am i doing wrong? Thanks in advance for the help
