The GIL's effect on the threads in your program is simple enough that you can write the principle on the back of your hand: "One thread runs Python, while N others sleep or await I/O." Python threads can also wait for a threading.Lock or other synchronization object from the threading...
在Win32和Linux, Solaris, MacOS, BSD等大多数类Unix系统上运行时,Python支持多线程编程。Python使用POSIX兼容的线程,即pthreads。 默认情况下,源码安装的版本在2.0及以上的python; win32的安装包中; 线程默认是打开的。 bogon:~ elaine$ python Python 2.7.10 (default, Feb 7 2017, 00:08:15) [GCC 4.2.1...

Imagine vanilla Python as a single needle and GIL as a single line of thread. With that needle and thread, a shirt is made. Its quality is amazing, but perhaps it could have been made more efficiently while maintaining that same quality. In that vein, what if we can workaroun...
add Height property, set ThreadCount to readonly ** if you still want to use ThreadCount you can do so in the python console. Select thread profile, Ctrl+Shift+P to send to the console. Enter in the console: obj.ThreadCount = 10. It can still also be used in expressions, such as...
