python - array.shape() giving error tuple not callable

I have a 2D numpy array called results, which contains its own array of data, and I want to go into it and use each list:

for r in results:
    print "r:"
    print r
    y_pred = np.array(r)
    print y_pred.shape()

This is the output I get:

r:

Traceback (most recent call last):
  File "C:UsersappDocumentsPython Scriptsgbc_classifier_test.py", line 93, in <module>
    print y_pred.shape()
TypeError: 'tuple' object is not callable

I don't understand why y_pred is not a regular array and why it's being considered a tuple, I've assigned it to be an array using r.

shape is just an attribute, not a method. Just use y_pred.shape (no parentheses).

(The error message isn't telling you that y_pred is a tuple, it's telling you that y_pred.shape is a tuple.)
