Solve the following python programming problem given the following code:
@ pytest.yield_fixture (scope = 'session', params = ['zeros', 'random']) 
def testdata(request, tmpdir_factory) : 
    (count, size) = (10, (1000 * 1000)) 
    p = tmpdir_factory.mktemp ('data') 
    data_type = request.param 
    if (data_type == 'zeros') : 
        def data(size) : 
            return (b'0' * size) 
if (data_type == 'random') : 
        def data(size) : 
            return os.urandom (size) 
for i in range (count) : 
        with open (str (p.join (str (data_type))), 'wb') as f : 
            f.write (data (size)) 
(yield str (p)) 
    p.remove (rec = 1) 

    
    

    Fix the buggy line: with open (str (p.join (str (data_type))), 'wb') as f :
