Create a 2D vector from a 1D vector in Python

Question

• I have a vector with the following values:

  a = [10, 20, 30, 40, 50, 60, 70, 80]

• I need to create 2D vector with these values. For example, it would have to look like this:

  b = [[10, 20], [30, 40], [50, 60], [70, 80]]

Please, could someone help me with this?

Thanks in advance, to those who can.

Answer 1

You can do something like this:

b = [a[i:i+2] for i in range (0, len(a), 2]
