Fix the perceptron algorithm when iterating over weights

Hi, thanks for the content. At 9:04 min you are showing your fit function. Inside there are some steps to update the weights. You update apart weights[0] according to x_0 (with x_0 = 1). But the rest of the weights have to be updated so you are doing a loop to do so. Would it be "for f_i in range(1,num_row)" instead of "for f_i in range(num_row)" ? Because if I understand here you are updating again weights[0] in the first iteration of the loop. Pardon me if I'm wrong. Thanks in advance for your answer.
