Hi Hamid,

Check the cost equation. The syntax error that you are seeing is because you are missing a parenthesis to close the numpy function that does the dot product. The name of the numpy function to calculate the dot product is np.dot, not np.dpt. Also, double check the derivation of the cost function to make sure you are calculating the cost function correctly.
