numpy array from list 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: numpy array from list

>>> a = [1, 2]
>>> np.asarray(a)
array([1, 2])

Example 5: convert list to numpy array

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

Example 6: np list to np

import numpy as np
a = np.array( [[2,3,4], [3,4,5]] )
