Below code is in pine script.

ta.sma(math.abs(src - out), 499)

I am trying to write code in Python for the above statement but not able to match trading view values.
As per my understanding, I wrote this code but it is not working.

out is a fixed value

sma_499 = sma(src, out, len(data))
print(sma_499)


def sma(src, out, window_size):
    
    sum = 0.0
    for i in range(window_size):
        print(abs(src[i]-out)/window_size)
        sum = sum + (abs(src[i]-out) / window_size)
    # print(sum)
    return sum

Need to print SMA values for each candle.
