Numpy str_len() function

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 :

# 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 :

# 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]
