numpy.core.defchararray.count(arr, sub, start=0, end=None)
is another function for doing string operations in numpy.It returns an array with the number of non-overlapping occurrences of substring sub in the range start to 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 :
# Python program explaining # numpy.char.count() method # importing numpy as 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 # importing numpy as 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 = 'a' , start = 1 , end = 8 )
print ( "Output array: " , out_arr)

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