Solve the following python programming problem given the following code:
def apiDecorator(api_type) : 
    def _apiDecorator(func) : 
        lines = [''] 
        marked = False 
        if (not func.__doc__) : 
            func.__doc__ = func.__name__ 
lines = func.__doc__.split ('
') 
        for (idx, line) in enumerate (lines) : 
            if ('@' in line) : 
                l = line.replace ('\t', '        ') 
                l2 = line.lstrip () 
                indent = (len (l) - len (l2)) 
                lines.insert (idx, ((' ' * indent) + ('(%s)' % api_type))) 
                marked = True 
                break 
if (not marked) : 
            lines [0] = (lines [0] + (' (%s)' % api_type)) 
try : 
            func.__doc__ = '

except TypeError :

return func 
return api_type
