我需要在同一个文本文件中为多个程序写入文本日志文件，我以为我需要某种锁定机制，但是后来我写了一个简单的多线程，并注意到某些日志没有写到最终目录文本文件？
def abc1Thread():
import portalocker
print ("-----------------abc1-Thread --------------------")
g = open("testFile", "a")
cnt = 0
f1 = open("A.txt", "a")
while (True):
cnt = cnt+1
if cnt == 10: break
print ("abc1Thread: cnt --> ",cnt+1)
f1.write("abc1Thread: cnt --> "+ str(cnt)+ "\n")
print ("close file handle: "+ str(f1))
f1.close()
def abc2Thread():
import portalocker
print("-----------------abc2-Thread --------------------")
cnt = 0
f2 = open("A.txt", "a")
while (True):
cnt = cnt+1
if cnt == 10: break
print("abc2Thread: cnt --> ", cnt)
f2.write("abc2cThread: cnt --> "+str(cnt)+"\n")
print ("close file handle: "+ str(f2))
f2.close()
def fileWriteShare():
thrd1 = threading.Thread(target=abc1Thread, args=[])
thrd2 = threading.Thread(target=abc2Thread, args=[])
thrd1.start()
thrd2.start()
如何在Windows python中锁定和解锁到文本文件，以便所有程序都能可靠地写入
