numpy.core.defchararray.rjust(arr, width, fillchar=' ') is another function for doing string operations in numpy. It returns an array with the elements of arr right-justified in a string of length width.It fills remaining space of each array element using fillchr parameter.If fillchr is not passed then it fills remaining spaces with blank space.
Parameters: arr : array_like of str or unicode.Input array. width : The final width of the each string . fillchar : The character to fill in remaining space. Returns : [ndarray] Output right justified array of str or unicode, depending on input type.Code #1 :
# Python program explaining
# numpy.char.rjust() method
# importing numpy
import numpy as geek
# input array
in_arr = geek.array(['Numpy', 'Python', 'Pandas'])
print ("Input array : ", in_arr)
# setting the width of each string to 8
width = 8
# output array when fillchar is not passed
out_arr = geek.char.rjust(in_arr, width)
print ("Output right justified array: ", out_arr)
Output:
Code #2 :
Input array : ['Numpy' 'Python' 'Pandas'] Output right justified array: [' Numpy' ' Python' ' Pandas']
# Python program explaining
# numpy.char.rjust() method
# importing numpy
import numpy as geek
# input array
in_arr = geek.array(['Numpy', 'Python', 'Pandas'])
print ("Input array : ", in_arr)
# setting the width of each string to 8
width = 8
# output array
out_arr = geek.char.rjust(in_arr, width, fillchar ='*')
print ("Output right justified array: ", out_arr)
Output:
Code #3 :
Input array : ['Numpy' 'Python' 'Pandas'] Output right justified array: ['***Numpy' '**Python' '**Pandas']
# Python program explaining
# numpy.char.rjust() method
# importing numpy
import numpy as geek
# input array
in_arr = geek.array(['1', '11', '111'])
print ("Input array : ", in_arr)
# setting the width of each string to 5
width = 5
# output array
out_arr = geek.char.rjust(in_arr, width, fillchar ='-')
print ("Output right justified array: ", out_arr)
Output:
Input array : ['1' '11' '111'] Output right justified array: ['----1' '---11' '--111']
