In this post, we are going to discuss the ways we can find the length of each string element in a given numpy array.
Problem # 1: Given an empty array whose underlying data has string type. Find the length of each element in a given object.
Solution: we're going to use numpy.vectorize ()
to find the length of each element in a given numpy array object.
# import numpy library as np
import
numpy as np
# Create an empty array
arr
=
np.array ([
'New York'
,
' Lisbon'
,
'Beijing'
,
' Quebec'
])
# Print array
print
(arr)
Output:
We will now use numpy.vectorize ()
to find the length of each item in a given array object numpy.

Output:
As we can see in the output, we have successfully computed the length of each string element in the given numpy array object.
Problem # 2: An array is given with an empty array, the underlying data of which is of a string type. Find the length of each element in a given object.
Solution: We're going to use a list comprehension technique to find the length of each element in a given array object.

Output:
We will now use a list comprehension technique to find the length of each element in a given numpy array object.

Output:
Like us we see in the output, we have successfully computed the length of each string element in the given numpy array object.
