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 :
import numpy as geek
in_arr = geek.array(['Numpy', 'Python', 'Pandas'])
print ("Input array : ", in_arr)
width = 8
out_arr = geek.char.rjust(in_arr, width)
print ("Output right justified array: ", out_arr)
|
Output:
Input array : ['Numpy' 'Python' 'Pandas']
Output right justified array: [' Numpy' ' Python' ' Pandas']
Code #2 :
import numpy as geek
in_arr = geek.array(['Numpy', 'Python', 'Pandas'])
print ("Input array : ", in_arr)
width = 8
out_arr = geek.char.rjust(in_arr, width, fillchar ='*')
print ("Output right justified array: ", out_arr)
|
Output:
Input array : ['Numpy' 'Python' 'Pandas']
Output right justified array: ['***Numpy' '**Python' '**Pandas']
Code #3 :
import numpy as geek
in_arr = geek.array(['1', '11', '111'])
print ("Input array : ", in_arr)
width = 5
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']
