Can you run this and tell why a is not equal to x_copy?
#Define x,y and swap_inds
x = np.array([1, 2, 3, 4])
y = np.array([4, 3, 2, 1])
swap_inds = np.random.random(size=len(x)) < 0.5
#Print out swap_inds
print(swap_inds)
#Method 1
x_copy = np.copy(x)
y_copy = np.copy(y)
x_copy[swap_inds] = y[swap_inds]
print(x_copy)
#Method 2
a = x_copy[swap_inds]
b = y[swap_inds]
a=b
print(a)
