You can use zip function:

for row in zip(b1, b2, b3):
    for elem in row:
        print(elem)

yes, but if i want to loop over them all together not just row[0], row[1], row[2] becaus i want to use them a function

Yelyzaveta Velizhanina Over a year ago

What do you mean by "loop over them all together". For the loop I've posted the row at each iteration will be the 1D array with 3 elements, just like you specified -> array([99.83765958 98.95138005 97.81793785]), at the second iteration array([0.05817715, 0.36399226, 0.75565525]) and so on. If that is not what you want, then please explain more specifically.

yes but i dont every time to write 0,1,2,3,4, ...30 to finsih row[0] how can i specify it in an index

Autumn89 Over a year ago

row[i] so it loops over the 3 arrays together row by row 5 times but i dont know how to do it

Do inner loop for elem in row. Otherwise, it is hard to understand what do you want.
