The **`ljust` method** returns a left-justified string of length as width by adding a specified fill character to the end of the string.

#    
#  Syntax

```
string.ljust(width, fillchar)
```

#    
#  Parameters

- `width`: The resulting string length. 

- `fillchar`: Fill character to be added at the end of the string. It is an optional value. By default, the space will be added. 

##   
## Return Value

* If the `width` is greater than the `length` of the string then the specified fill character will be added at the end of the string to make the string length equal to the passed `width` value.

*  If the `width` is greater than the `length` of the string then the original string is returned.


##   
## Example

string = "123"

print(string.ljust(4, '$'))
print(string.ljust(5, '*'))
print(string.ljust(10, '#'))
print(string.ljust(1, '#'))

In the code above, we created a `123` string and then:

* Called `ljust` method where the `width` is `4` and `fillchar` is `$`. In this case, the string length is three, and the width is four. Four is greater than three and 4-3 = 1, so one `$` is added to the end 
of the string and `123$` is returned.

* Called `ljust` method where the `width` is `5` and `fillchar` is `*`. In this case, the string length is three, and the width is Five. Five is greater than three and 5-3 = 2, so two `*` are added to the end 
of the string and `123**` is returned.

* Called `ljust` method where the `width` is `10` and `fillchar` is `#`. In this case, the string length is three, and the width is ten. Ten is greater than three and 10-3 = 7, so seven `#` are added to the end 
of the string and `123#######` is returned.

* Called `ljust` method where the `width` is `1` and `fillchar` is `#`. In this case, the string length is three, and the width is one. One is smaller than three, so the string and `123` will be returned.




In the code above, we created a `123` string and then:

* Called `ljust` method where the `width` is `4` and `fillchar` is `＄`. In this case, the string length is three, and the width is four. Four is greater than three and 4-3 = 1, so one `＄` is added to the end 
of the string and `123＄` is returned.

* Called `ljust` method where the `width` is `5` and `fillchar` is `*`. In this case, the string length is three, and the width is Five. Five is greater than three and 5-3 = 2, so two `*` are added to the end 
of the string and `123**` is returned.

* Called `ljust` method where the `width` is `10` and `fillchar` is `#`. In this case, the string length is three, and the width is ten. Ten is greater than three and 10-3 = 7, so seven `#` are added to the end 
of the string and `123#######` is returned.

* Called `ljust` method where the `width` is `1` and `fillchar` is `#`. In this case, the string length is three, and the width is one. One is smaller than three, so the string and `123` will be returned.




What is a string.ljust in Python?

The ljust method in Python returns a left-justified string of a specified width by adding a specified fill character to the end.
