String rjust() and ljust() in python()

Last Updated : 08 Jan, 2018

1. String rjust() The string rjust() method returns a new string of given length after substituting a given character in left side of original string. Syntax:

string.rjust(length, fillchar)

Parameters:

length: length of the modified string. If length is less than or equal to the length of the original string then original string is returned. fillchar: (optional) characters which needs to be padded. If it's not provided, space is taken as a default argument.

Returns:

Returns a new string of given length after substituting a given character in left side of original string.

Example

Python3

# Python program to demonstrate working of 
# rjust()
string = 'geeks'
length = 8

# If no fill character is provided, space
# is used as fill character
print(string.rjust(length))

Output:

   geeks

Example

Python3

# example string
string = 'geeks'
length = 8
fillchar = '*'

print(string.rjust(length, fillchar))

Output:

***geeks

2. String ljust() The string ljust() method returns a new string of given length after substituting a given character in right side of original string. Syntax:

string.ljust(length, fillchar)

Parameters:

length: length of the modified string. If length is less than or equal to the length of the original string then original string is returned. fillchar: (optional) characters which needs to be padded. If it's not provided, space is taken as a default argument.

Returns:

Returns a new string of given length after substituting a given character in right side of original string.

Example 1

Python3

# example string
string = 'geeks'
length = 8

# If no fill character is provided, space
# is used as fill character.
print(string.ljust(length))

Output: (Three spaces are printed after geeks)

geeks

Example 2

Python3

# example string
string = 'geeks'
length = 8
fillchar = '*'

# print left justified string
print(string.ljust(length, fillchar))

Output:

geeks***
