Python String ljust() Method

​The ljust() function returns a new copy of the original string with the fill characters that are passed in the 'character' argument from the right. If no character is passed in the 'character' argument, blank white spaces will be added. With a number passed to the length argument to specify the total number of characters for the string

string. adjust(length, character)

In the following example, we will not pass any characters or symbols to the "character" argument. By default, the blanks on the right will be filled with white space. With "15" passed to the length argument to specify the total number of characters for the string

first_name = "ahmed"
last_name =  "obaid"
print(first_name.ljust(15), last_name)

The output will be:

ahmed           obaid

Example:

string = "ahmed obaid"
a = string.ljust(20)
print(a, "this is my name.")

 The output will be:

ahmed obaid          this is my name.

In the following example, we will pass the $ character to the "character" argument to fill in the blanks from the right. Passing "18" to the length argument to specify the total number of characters for the string

Example:

string  = "ahmed obaid"
print(string.ljust(18, '$'))

The output will be:

ahmed obaid$$$$$$$

In the following example, we will pass the underscore "_" to the "character" argument to fill in the blanks on the right. Passing "10" to the length argument to specify the total number of characters for the string

Example:

string = "ahmed"
print(string.ljust(10, '-'))

The output will be:

ahmed-----
