Python String ljust() Method Examples

In the previous article, we have discussed Python Program for String join()
ljust() Function in Python:

The ljust() method will left align the string, using a specified character as the fill character (space is the default).

Syntax:

string.ljust(Length, character)

Parameters

Length: This is required. It is the length of the string returned.

character: This is optional. Fills the character in the missing space( right of the string). The default value is ” ” (space).

Examples:

Example1:

Input:

Given first string = "python"
Given length = 15 
Given character = '-'

Output:

The above given first string is : python
The given first string after applying ljust() function: python---------

Note: If you don’t give any character then it takes space by default.

Example2:

Input:

Given second string = "GOODMORNING"
Given length = 17
Given character = '#'

Output:

The above given second string is : GOODMORNING
The given second string after applying ljust() function: GOODMORNING######

Method #1: Using Built-in Functions (Static Input)

Approach:

Give the first string as static input and store it in a variable.
Give the length as static input and store it in another variable.
Give the character as static input and store it in another variable.
Apply ljust() method to the given string for the given length and the character which will left align the string, using a specified character as the fill character (space is the default).
Print the above-given string.
Print the above-given string after applying the ljust() function.
Similarly, do the same for the other string and print the result string.
The Exit of Program.

Below is the implementation:

# Give the first string as static input and store it in a variable.
gvn_fststr = "python"
# Give the length as static input and store it in another variable.
gvn_lengt = 15
# Give the character as static input and store it in another variable.
gvn_chactr = '-'
# Apply ljust() method to the given string for the given length and the
# character which will left align the string, using a specified character
# as the fill character (space is the default).
# Store it in another variable.
rslt_str1 = gvn_fststr.ljust(gvn_lengt, gvn_chactr)
# Print the above given string
print("The above given first string is :", gvn_fststr)
# Print the above given string after applying ljust() function.
print("The given first string after applying ljust() function:", rslt_str1)
# Similarly do the same for other string and print the result string.
gvn_scndstr = "GOODMORNING"
gvn_lengt2 = 17
gvn_chactr2 = '#'
rslt_str2 = gvn_scndstr.ljust(gvn_lengt2, gvn_chactr2)
print("The above given second string is :", gvn_scndstr)
print("The given second string after applying ljust() function:", rslt_str2)

Output:

The above given first string is : python
The given first string after applying ljust() function: python---------
The above given second string is : GOODMORNING
The given second string after applying ljust() function: GOODMORNING######

Method #2: Using Built-in Functions (User Input)

Approach:

Give the first string as user input using the input() function and store it in a variable.
Give the length as user input using the int(input()) function and store it in another variable.
Give the character as user input using the input() function and store it in another variable.
Apply ljust() method to the given string for the given length and the character which will left align the string, using a specified character as the fill character (space is the default).
Print the above-given string.
Print the above-given string after applying the ljust() function.
Similarly, do the same for the other string and print the result string.
The Exit of Program.

Below is the implementation:

# Give the first string as user input using the input() function and store it in a variable.
gvn_fststr =  input("Enter some random string = ")
# Give the length as user input using the int(input()) function and store it in another variable.
gvn_lengt = int(input("Enter some random number = "))
# Give the character as user input using the input() function and store it in another variable.
gvn_chactr = input("Enter some random charcter = ")
# Apply ljust() method to the given string for the given length and the
# character which will left align the string, using a specified character
# as the fill character (space is the default).
# Store it in another variable.
rslt_str1 = gvn_fststr.ljust(gvn_lengt, gvn_chactr)
# Print the above given string
print("The above given first string is :", gvn_fststr)
# Print the above given string after applying ljust() function.
print("The given first string after applying ljust() function:", rslt_str1)
# Similarly do the same for other string and print the result string.
gvn_scndstr = input("Enter some random string = ")
gvn_lengt2 = int(input("Enter some random number = "))
gvn_chactr2 = input("Enter some random charcter = ")
rslt_str2 = gvn_scndstr.ljust(gvn_lengt2, gvn_chactr2)
print("The above given second string is :", gvn_scndstr)
print("The given second string after applying ljust() function:", rslt_str2)

Output:

Enter some random string = hello
Enter some random number = 10
Enter some random charcter = %
The above given first string is : hello
The given first string after applying ljust() function: hello%%%%%
Enter some random string = goodmorning
Enter some random number = 25
Enter some random charcter = $
The above given second string is : goodmorning
The given second string after applying ljust() function: goodmorning$$$$$$$$$$$$$$
