convert list of list to numpy array code example
Example 1: numpy list to array
# importing library
import numpy
# initilizing list
lst = [1, 7, 0, 6, 2, 5, 6]
# converting list to array
arr = numpy.array(lst)
# displaying list
print ("List: ", lst)
# displaying array
print ("Array: ", arr)
Example 2: np.array to list
>>> a = np.array([1, 2])
>>> list(a)
[1, 2]
>>> a.tolist()
[1, 2]
Example 3: convert list of lists to numpy array matrix python
x=[[1,2],[1,2,3],[1]]
y=numpy.array([numpy.array(xi) for xi in x])
type(y)
# <type 'numpy.ndarray'>
type(y[0])
# <type 'numpy.ndarray'>
