Solve the following python programming problem given the following code:
def __call__(self, task_that_copies) : 
    task_that_copies = self.requires_decorator (self) 
    @ task_wraps (task_that_copies) 
    class Wrapped (task_that_copies) : 
        def run(_self) : 
            (i, o) = (_self.input (), _self.output ()) 
            f = o.open ('w') 
            for line in i.open ('r') : 
                f.write (line) 
f.close () 
return Wrapped 

    
    

    Fix the buggy line: task_that_copies = self.requires_decorator (self)

#Here is Python code to fix the buggy line: task_that_copies = self.

task_that_copies = self.requires_decorator (task_that_copies)
