How to reshape an array?

Question

Python

There are multiple arrays that have the same length but different shapes. All of them look something like this when printed:
a = [1 4 5 8 12 22 98 ...]
One of the arrays has the form (80, ), the second: (80, 2, 1), the third: (80, 1, 1). How to bring all arrays to the same shape?

Answer 1

shape = (80, ) just means that the array is one-dimensional. I think the original problem is something else.
