Python: Get a string made of 4 copies of the last two characters of a specified string

Python String: Exercise-17 with Solution

Repeat last 2 chars of a string 4 times.

Write a Python function to get a string made of 4 copies of the last two characters of a specified string (length must be at least 2).

Sample Solution:

Python Code:

# Define a function named insert_end that takes one argument, 'str'.
def insert_end(str):
    # Extract the last two characters from the input string 'str' and store them in 'sub_str'.
    sub_str = str[-2:]
    
    # Multiply 'sub_str' by 4 and return the result, effectively repeating the last two characters four times.
    return sub_str * 4

# Call the insert_end function with different input strings and print the results.
print(insert_end('Python'))    # Output: 'onononon'
print(insert_end('Exercises')) # Output: 'eseseses'

Sample Output:

onononon                                                                                                      
eseseses

Python Code Editor:

Previous: Write a Python function to insert a string in the middle of a string.
Next: Write a Python function to get a string made of its first three characters of a specified string. If the length of the string is less than 3 then return the original string.
