operations with empty strings | rjust () function

numpy.core.defchararray.rjust (arr, width, fillchar = & # 39; & # 39;) — this is another function for doing string operations in numpy. It returns an array with arr elements right-aligned in a string of length width. It fills the remaining space of each array element with fillchr the fillchr fillchr fillchr is not passed, then it fills the 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   # numpy import import numpy as geek   # input array in_arr = geek.array ([ ’Numpy’ , ’Python’ , ’ Pandas’ ]) print ( "Input array:" , in_arr)    # setting the width of each lines by 8 width = 8   # output array when fillchar is not passed ou t_arr = geek.char.rjust (in_arr, width) print ( "Output right justified array:" , out_arr)

Exit:

 Input array: [’Numpy’’ Python’ ’Pandas’] Output right justified array: [’ Numpy’ ’Python’’ Pandas’] 

Code # 2:

# Python program explaining # numpy.char.rjust () method   # numpy import import numpy as geek   # input array in_arr = geek.array ([ ’ Numpy’ , ’Python’ , ’Pandas’ ]) print ( "Input array:" , in_arr)    # set the width of each line to 8 width = 8    # output array out_arr = geek.char.rjust (in_arr, width, fillchar = ’ * ’ ) print ( "Output right justified array:" , out_arr)

Exit :

 Input array: [’Numpy’’ Python’ ’Pandas’] Output right justified array: [’ *** Numpy’ ’** Python’’ ** Pandas’] 

Code # 3:

# Python program explaining # numpy.char.rjust () method   # numpy import import numpy as geek   # input array in_arr = geek.array ([ ’1’ , ’ 11’ , ’111’ ]) print ( "Input array:" , in_arr)   # set the width of each line to 5 width = 5   # output array out_arr = geek.char.rjust (in_arr, width, fillchar = ’-’ ) print ( "Output ri ght justified array: " , out_arr)

Output :

 Input array: [’1’’ 11’ ’111’] Output right justified array: [’ ---- 1’ ’--- 11’ ’--111’]
