Solve the following python programming problem given the following code:
# @run_if_any without arguments
    @process_slot("a", "b", "c", "d") 
    @run_if_any # run if at least one among "a", "b", "c", "d" slots contains new data
    def run_step(self, run_number, step_size, howlong):
        with self.context as ctx:
            pass # do something

    # @run_if_any with arguments    
    @process_slot("a", "b", "c", "d") 
    @run_if_any("b", "d") # run if at least one between b" and "d" slots contains new data
    def run_step(self, run_number, step_size, howlong):
        with self.context as ctx:
            pass # do something
Given the above code, generate some markdown instructions for it.

#Here is the Python code you requested.

Run condition decorators
These decorators define the conditions that allow the execution of the decorated run_step () method.
They are :

@run_if_any with possible extension @and_any
@run_if_all with possible extension @or_all
@run_always

The @run_if_any decorator
Allows execution of the decorated run_step() method if and only if at least one entry contains new data. It can be used with or without arguments which are slot names. When called without arguments it applies to all entry slots:
