Python Exercise: Accept a hyphen-separated sequence of words as input and prints the sorted words

Last update on December 21 2024 07:24:04 (UTC/GMT +8 hours)

Write a Python program that accepts a hyphen-separated sequence of words as input and prints the words in a hyphen-separated sequence after sorting them alphabetically.

Sample Solution:

Python Code:

# Take user input and split it into a list based on the hyphen ("-") separator, creating a list named 'items'
items = [n for n in input().split('-')]

# Sort the elements in the 'items' list in lexicographical order (alphabetical and numerical sorting)
items.sort()

# Join the sorted elements in the 'items' list using the hyphen ("-") separator and print the resulting string
print('-'.join(items)) 

Sample Output:

green-red-black-white                                                                                         
black-green-red-white 

Explanation:

In the exercise above the code takes user input, splits it based on the hyphen -, and stores the parts in a list called 'items'. It then sorts these items in lexicographical order (ascending order for text strings and numerical order for numbers). Finally, it joins the sorted items using the hyphen - as a separator and prints the resulting string.
