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: python numpy array to list

# Basic syntax:
numpy_array.tolist()

# Example usage:
your_array = np.array([[1, 2, 3], [4, 5, 6]])
your_array
--> array([[1, 2, 3],
           [4, 5, 6]])

your_array.tolist()
--> [[1, 2, 3], [4, 5, 6]]

Example 4: convert list to numpy array

import numpy as np
npa = np.asarray(Lists, dtype=np.float32)

Example 5: 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 6: list of list to numpy array

>>> lists = [[1, 2], [3, 4]]
>>> np.array(lists)
array([[1, 2],
       [3, 4]])
