Name
flat
Synopsis
a
.flat is an
attribute that contains an array with rank 1 and of the same size as
a, sharing
a’s data. Indexing or
slicing a
.flat lets you
access or change a’s
elements through this alternate view of a.
Trying to access a
.flat
raises a TypeError exception if
a is noncontiguous. When
a is contiguous,
a
.flat is in row-major
order. This means that, for example, when
a’s shape is
(7,4) (i.e., a is a
two-dimensional matrix with seven rows and four columns),
a
.flat[
i
]
is the same as
a
[divmod(
i
,4)]
for all i in range(28).
