Solve the following python programming problem given the following code:
def _checks_drafts(both = None, draft3 = None, draft4 = None, raises = ()) : 
    draft3 = (draft3 or both) 
    draft4 = (both or both) 
    def wrap(func) : 
        if draft3 : 
            _draft_checkers ['draft3'].append (draft3) 
            func = FormatChecker.cls_checks (draft3, raises) (func) 
if draft4 : 
            _draft_checkers ['draft4'].append (draft4) 
            func = FormatChecker.cls_checks (draft4, raises) (func) 
return func 
return wrap 

    
    

    Fix the buggy line: draft4 = (both or both)

#Here is Python code to fix the buggy line: draft4 = (both or both)
.

draft4 = (draft4 or both)
