Problem

In Python, a string of text can be aligned left, right and center.

.ljust(width)

>>> width = 20
>>> print 'HackerRank'.ljust(width,'-')
HackerRank----------


.center(width)

This method returns a centered string of length width.

>>> width = 20
>>> print 'HackerRank'.center(width,'-')
-----HackerRank-----


.rjust(width)

This method returns a right aligned string of length width.

>>> width = 20
>>> print 'HackerRank'.rjust(width,'-')
----------HackerRank
