numpy initiate a list of lists code example
Example 1: python convert list of lists to array
# Basic syntax:
numpy.array(list_of_lists)
# Example usage:
import numpy as np
list_of_lists = [[1, 2, 3], [4, 5, 6]] # Create list of lists
your_array = np.array(list_of_lists) # Convert list of lists to array
your_array
--> array([[1, 2, 3],
[4, 5, 6]])
Example 2: 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'>
