Description
Passing a local variable to a del statement results in that variable being removed from the local namespace.
When exiting a function all local variables are deleted, so it is unnecessary to explicitly delete variables in such cases.
It is recommended to remove this del statement.
Not preferred:
def my_func():
task = do_some_task()
evaluate_task(task)
del task # This is unnecessary.
Preferred:
def my_func():
task = do_some_task()
evaluate_task(task)
