operations with empty strings | count () function



numpy.core.defchararray.count (arr, sub, start = 0, end = None) — this is another function for doing string operations in numpy. It returns an array with the number of non-overlapping occurrences of the substring sub at the beginning of the range: end.

Parameters:
arr: array_like of str or unicode.
sub: [str or unicode] The substring which to be searched.
start: [int, optional] The starting location in each string.
end: [int, optional] The ending location in each string.

Returns: [ndarray] the number of non-overlapping occurrences of substring sub.

Code # 1:

# Program Python explaining
# numpy.char.count () method

 
# import numy as a geek

import numpy as geek

  
# input arrays

in_arr = geek.array ([ `Sayantan` , ` Sayan ` , `Sayansubhra` ])

print ( "Input array:" , in_arr) 

 
# output arrays

out_arr = geek.char.count (in_arr, sub = `an` )

print ( " Output array: " , out_arr) 

Output :

 Input array: [`Sayantan`` Sayan `` Sayansubhra`] Output array: [2 1 1] 

Code # 2:

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

 
# import numy as a geek

import numpy as geek

  
# input arrays

in_arr = geek.array ([ `Sayantan` , ` Sayan`  , < / code> `Sayansubhra` ])

print ( "Input array:" , in_arr) 

 
# output arrays

out_arr = geek.char.count (in_arr, sub = `a` , start = 1 , end = 8 )

print ( " Output array: " , out_arr) 

Output :

 Input array: [`Sayantan`` Sayan `` Sayansubhra `] Output array: [3 2 2]
