numpy.core.defchararray.join(sep, arr) is another function for doing string operations in numpy. For each element in arr, it returns a copy of the string in which the string elements of array have been joined by separator.
Parameters:
sep : It joins elements with the string between them.
arr :Input array.Returns : Output array of str or unicode with joined elements.
Code #1 :
# Python program explaining# numpy.core.defchararray.join() method # importing numpy import numpy as geek # input array in_arr = geek.array(['Python', 'Numpy', 'Pandas'])print ("Input original array : ", in_arr) # creating the separatorsep = geek.array(['-', '+', '*']) out_arr = geek.core.defchararray.join(sep, in_arr)print ("Output joined array: ", out_arr) |
Output:
Input original array : ['Python' 'Numpy' 'Pandas'] Output joined array: ['P-y-t-h-o-n' 'N+u+m+p+y' 'P*a*n*d*a*s']
