Answer 1

if you're referring to a shape of a NumPy array, rather than a tuple

(your provided example does not represent a tuple):

given some array x with shape (680,), you can use x[...,np.newaxis] to expand it's dimension

---

toy example:

x = np.empty((680,))
print(x.shape)
x = x[..., np.newaxis]
print(x.shape)

out:

(680,)
(680, 1)
