What is a string.rjust() in Python?

The rjust method will return a right-justified string of length as width by adding a specified fill character to the beginning of the string.

Syntax

str.rjust(width, fillchar)

Parameters

  • width: The resulting string length.

  • fillchar: The character to be added at the start of the string. It is an optional value. By default, the space will be added. This parameter is optional.

Return value

  • If the width is greater than the length of the string, then the specified filchar will be added at the beginning of the string to make the string length equal to the passed width value.

  • If the width is less than the length of the string, then the original string is returned.

Code

string = "123"
print(string.rjust(4))
print(string.rjust(5, '*'))
print(string.rjust(10, '#'))
print(string.rjust(1, '#'))

In the code above, we created a string, 123. Then:

  • Called the rjust method with width as 4. In this case, the string length is 3 and the width is 4. 4 is greater than 3 and their difference is one, so one space (default fillchar) is added to the beginning of the string, and " 123" is returned.

  • Called the rjust method with width as 5 and fillchar as *. In this case, the string length is 3 and the width is 5. 5 is greater than 3 and their difference is two, so two * are added to the beginning of the string and **123 is returned.

  • Called the rjust method with width as 10 and fillchar as #. In this case, the string length is 3 and the width is 10. 10 is greater than 3 and their difference is seven, so seven # are added to the beginning of the string and #######123 is returned.

  • Called the rjust method with width as 1 and fillchar as #. In this case, the string length is 3 and the width is 1. 1 is smaller than 3, so the string and 123 will be returned.
