python多线程：阻塞可以线程化吗？

我正在尝试学习线程，以下是我的代码：

import threading, saspy

def sas_session(sas_string):
    sas=saspy.SASsession()
    sas.submit(sas_string)
    sas._endsas()       

if __name__ == "__main__":

    sas_string1='data aa.para_001;\n start = datetime(); \n slept=sleep(rand("Uniform")+10,1);\n ending=start+slept;\nrun;'

    t1 = threading.Thread(target=sas_session, args=(sas_string1,)) 

    t1.start()    
    t1.join()

我收到了错误信息：

需要很长时间才能完成，大概10秒左右。我想这是一个阻塞过程。这可能是原因吗？

它甚至不能进入

sas.submit（）

。它在

saspy.SASsession（）上失败了。

可能相关：@jordanm谢谢，它成功了，但我对这个修复程序一无所知。你能详细说明一下吗？我会等一会儿，看看是否有人能给出更详细的解释。谢谢，阿加尼无法详细说明，因为我从未在Windows上进行过任何开发。我只是在谷歌上搜索了“尚未调用CoInitialize”错误消息。

sas.submit(sas_string)
