That is the actual code I am using in a file named 'ex.py'. 
My Worker files are also named with a '.py' extension.
When I run my 'ex.py' through a command prompt, the 'Worker1.py' is executed in the same command prompt and starts an infinite loop. It never gets to the 'Worker2.py' part.
But I want my Workers to be executed in different command prompts.
