Numpy str_len() function

Last Updated : 05 May, 2020

numpy.char.str_len(arr) function is used for doing string operations in numpy. It returns the length of every string element wise.

Parameters: arr : array_like of str or unicode.Input array. Returns : [ndarray] Output Array of integer.

Code #1 :

Python3

# Python program explaining
# numpy.char.str_len() method 

# importing numpy 
import numpy as geek

# input array  
in_arr = geek.array(['geeks for geeks'])
print ("Input array : ", in_arr) 

# output array 
out_arr = geek.char.str_len(in_arr)
print ("Output array containing length: ", out_arr)

Output:

Input array :  ['geeks for geeks']
Output array containing length:  [15]

Code #2 :

Python3

# Python program explaining
# numpy.char.str_len() method 

# importing numpy 
import numpy as geek

# input array 
in_arr = geek.array(['Numpy', 'Python', 'Pandas'])
print ("Input array : ", in_arr) 


# output array 
out_arr = geek.char.str_len(in_arr)
print ("Output array containing length: ", out_arr)

Output:

Input array :  ['Numpy' 'Python' 'Pandas']
Output array containing length:  [5 6 6]
