I have 2 arrays containing zeros & ones. I want to perform hstack() on them but not getting the desired output.
Python Code..
import numpy as np
zeros = np.zeros(8)
ones = np.ones(8)
zerosThenOnes = np.hstack((zeros, ones)) # A 1 by 16 array
Current Output..
[ 0. 0. 0. 0. 0. 0. 0. 0. 1. 1. 1. 1. 1. 1. 1. 1.]
Expected Output..
[ 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 ]
I can't understand what silly mistake I'm doing.
You must tell numpy to return the values as integers
import numpy as np
zeros = np.zeros((8,), dtype=np.int)
ones = np.ones((8,), dtype=np.int)
zerosThenOnes = np.hstack((zeros, ones))
To print out zerosThenOnes
like this [0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1]
Use:
print([x for x in zerosThenOnes])
np.hstack((np.zeros(8), np.ones(8))).astype(int)
for np.array
output, or
map( int, np.hstack((np.zeros(8), np.ones(8))) )
for list
output
