If a Python program can be broken into subprograms who is processing do not depend on each other, then each of the subprogram can be run in parallel when the overall program is being run. This concept is known as parallel processing in Python. With multiprocessing This module can be used ...
I am running a tkinter GUI, I have created buttons to run various scripts, but when I run them the GUI beachballs and is unaccessible. How can I call these scripts and still be able to operate the GUI ?? i am trying to use subprocess: ...
总结:当系统有一个以上 CPU 时,则线程的操作有可能非并发。当一个 CPU 执行一个线程时,另一个 CPU 可以执行另一个线程,两个线程互不抢占 CPU 资源,可以同时进行,这种方式我们称之为并行(Parallel) 2. 采集对比 2.1 单线程 importrequestsdeftest(url):res=requests.get(url)returnresif__name__=='__main...
