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

In this tutorial, we are going to learn about rjust() and ljust methods of strings. Let's see one one.

rjust(length, [fillchar])

The method rjust() will return a new string after adding the fillchar at the beginning of the based on the length. The argument length is required whereas fillchar is not.

By default, the fillchar is a space. Let's see an example.

Example

# initialzing a string
string = 'tutorialspoint'
# rjust -> 25
print(string.rjust(25))

Output

If you run the above code, then you will get the following result.

tutorialspoint

We can give the fillchar as well. And it needs to be a single character and not a string. Let's an example.

Example

# initialzing a string
string = 'tutorialspoint'
# rjust -> 25
print(string.rjust(25, '#'))

Output

If you run the above code, then you will get the following result.

###########tutorialspoint

If we provide a string in-place of character, then we will get an error. Let's see an example.

Example

# initialzing a string
string = 'tutorialspoint'
# rjust -> 25
print(string.rjust(25, '###'))

Output

If you run the above code, then you will get the following result.

---------------------------------------------------------------------------
TypeError Traceback (most recent call last)

4 # rjust -> 25
----> 5 print(string.rjust(25, '###'))
TypeError: The fill character must be exactly one character long

ljust(length, [fillchar])

The method ljust() is opposite to the rjust() method.

The method ljust() will return a new string after adding the fillchar at the end of the string on the length. The argument length is required whereas fillchar is not.

By default, the fillchar is a space. Let's see an example.

Example

# initialzing a string
string = 'tutorialspoint'
# rjust -> 25
print(string.ljust(25))

Output

If you run the above code, then you will get the following result.

tutorialspoint

We can give the fillchar as well. And it needs to be a single character and not a string. Let's an example.

Example

# initialzing a string
string = 'tutorialspoint'
# rjust -> 25
print(string.ljust(25, '#'))
tutorialspoint###########

Output

If you run the above code, then you will get the following result.

tutorialspoint###########

If we provide a string in-place of character, then we will get an error. Let's see an example.

Example

# initialzing a string
string = 'tutorialspoint'
# rjust -> 25
print(string.ljust(25, '###'))

Output

If you run the above code, then you will get the following result.

---------------------------------------------------------------------------
