线程差异（target = sample_function），args = [arg1]）thread.thread.thread（target = sample_function（arg1））
我一直在研究循环内的线程功能，这引起了我的注意。 如果我执行
threading.Thread(target=sample_function(arg1))
它，它实际上并不像预期的那样多线程，而是必须在启动第二个之前执行整个 sample_function() 。 事实证明我必须更改为这一行才能获得正确的多线程
threading.Thread(target=sample_function, args=[arg1])
有人能告诉我为什么会这样吗？
谢谢！
I've been working around a threading functionality inside a loop and this caught my attention.
If I execute
threading.Thread(target=sample_function(arg1))
It doesn't actually multithread as expected, instead it had to go through the entire sample_function() before starting the second one.
Turns out i had to change to this line instead to get proper multithreading
threading.Thread(target=sample_function, args=[arg1])
Can anyone tell me why is this so?
Thanks!

target=预计是可调用的。sample_function是可调用的。sample_function(arg1)不可调用，而是函数调用的返回值。我假设
sample_function(arg1)返回None这使得threading.Thread(target=sample_function(arg1))不运行任何内容。出于寓教于乐的目的：使示例函数返回一个字符串，看看会发生什么
The
target=is expected to be a callable.sample_functionis callable.sample_function(arg1)isn't callable, but the return of the function call.I assume that
sample_function(arg1)returnsNonewhich makesthreading.Thread(target=sample_function(arg1))run nothing.For edutainment purposes: make samplefunction return a string and see what happens
