Synopsis
The
a
.shape attribute is a
tuple with one item per axis of a, giving
the length of that axis. You can assign a sequence of integers to
a
.shape to change the
shape of a, but
a’s size (the total
number of elements) must remain the same. When you assign to
a
.shape another
sequence s, one of
s’s items can be
-1, meaning that the length along that axis is
whatever is needed to keep
a’s size unchanged.
However, the product of the other items of
s must evenly divide
a’s size, or else the
reshaping raises an exception. When you need to change the total
number of elements in a, call function
resize (covered in Section 15.6.9 later in this chapter).
