I want to assign a new value to [i + 1][j] of array, but it seems there is a problem.
a = np.array(['#', '#', '#', '#', '#', '#','#', ' ', ' ', 'A', ' ', '#',
'#', ' ', '#', 'P', ' ', '#',
'#', ' ', ' ', ' ', ' ', '#',
'#', 'P', ' ', ' ', ' ', '#',
'#', '2', ' ', ' ', ' ', '#',
'#', '#', '#', '#', '#', '#'])
print(len(a))
b = np.reshape(a,(7,6))
i = 0
j = 0
print(b[i + 1][j])
b[i + 1][j] = 'AP'
print(b[i + 1][j])
output:
#
A
How can I assign "AP" instead of "#" ?
b.dtype
(see data type objects ) is <U1
which is a unicode string of length 1.
you could fix that with
a = np.array(['#',..., '#'], dtype='<U2')
which will then accept strings up to length 2.
