In this article, you will learn how to convert a list of lists into a NumPy array using numpy.array().

In this article, you will learn how to convert a list of lists into a NumPy array using numpy.array().

Step 1: Create a new list of lists or nested lists

ListofLists = [[1, 2, 3, 4, 5], [6, 7, 8, 9 ,10]]

# Display lists
print(ListofLists)

# Display type
print(type(ListofLists))

Output:

[[1, 2, 3, 4, 5], [6, 7, 8, 9, 10]]
<class 'list'>

Step 2: Convert a list of lists into a numpy array

# import required python library
import numpy

# You can convert it using numpy.array
my_array = numpy.array(ListofLists)

# Display converted nested arrays
print(my_array)

# Display type
print(type(my_array))

Output:

[[ 1  2  3  4  5]
 [ 6  7  8  9 10]]
<class 'numpy.ndarray'>
