What is the numpy.rjust() function from NumPy in Python?

Overview

The char.rjust() function in Python is used to return an array with the length of an input array that is right-justified in a string of a given length.

Syntax

char.rjust(a, width, fillchar=' ')

Parameter

The char.ljust() function takes the following parameter values:

  • a: This represents the input array.
  • width: This represents the length of the output string.
  • fillchar: This represents the character that is used for padding.

Return value

The char.rjust() function returns an array of strings or Unicode. The returned value depends on the input type in the function.

Example

Let’s look at the code below:

import numpy as np
# implementing the char.rjust() function 
myarray = np.char.rjust('Theo', 10, fillchar = '*')
print(myarray)

Explanation

  • Line 4: We create a string character called "Theo". Then, we choose to return an array of string with a length of 10, which is to be filled with the character "*" at a particular number of times just before "Theo" is added. It makes the resulting array a total length of 10 characters.
