Python threading arguments passing

I would like to understand the difference between the ways we can pass arguments to threads and if this has any effect on thread safety.

I am using python 3.7.3 and both instances of the code runs fine for me.

Example 1:
thread = threading.Thread(target=MultiHandler().handle, args=(argument))

Example 2:
thread = threading.Thread(target=MultiHandler().handle(argument))

Python allows both args and kwargs in threading as arguments. And that can be used to make decisions inside a function. And it's the callable function where thread safety applies not on the arguments.

target should be the callable object to be invoked, not the result of the function call,
unless your 2nd sample function returns another callable (target=MultiHandler().handle(argument) returns ---> callable).
