Changing the len() function in Python [closed]
Before, in my code I had this vector: x = [ [0.72,0.82], [0.91,-0.69], [0.03,0.93], [0.12,0.25], [0.96,0.47], [0.8,-0.75] ] And there was this for that worked correctly: for k in range(1,10): for i in range(0,len(x)): sum = 0 for j in range(0,len(x[i])): sum += x[i][j] * w[j] I have to make a change in the vector: x = [ [0.72,0.82,-1], [0.91,-0.69,-1], [0.03,0.93,-1], [0.12,0.25,-1], [0.96,0.47,-1], [0.8,-0.75,-1] ] In this sense, I realize that I need to make a modification in my len(x[i]) so that the previous result is the same as now, I tried to len(x), but it did not work, what could I do?
just have j go from 0 to 1 then. (or if you want, "len(x[i]) - 1") for k in range(1,10): for i in range(0,len(x)): sum = 0 for j in range(2): sum += x[i][j] * w[j]
