Hello
I am trying to create multiple thread through the below program but I am

Traceback (most recent call last):

TypeError: first arg must be callable
The first argument should be the function. You're calling proc(f) and
the passing its result.
Also, start_new_thread starts the thread running immediately and
returns its identifier, an int.
