It is used to iterate over any sequences such as list, tuple, string, etc. The syntax of the for loop is: for val in sequence: # statement (s) … WebThis works; however when the matrix x is very large, computing an explicit loop in Python could be slow. Note that adding the vector v to each row of the matrix x is equivalent to forming a matrix vv by stacking multiple copies of v vertically, then performing elementwise summation of x and vv. We could implement this approach like this: fcs credit
