Python: Prints the unique words in sorted form from a comma separated sequence of words

Last update on March 21 2025 12:53:20 (UTC/GMT +8 hours)

Sort distinct words in comma-separated input.

Write a Python program that accepts a comma-separated sequence of words as input and prints the distinct words in sorted form (alphanumerically).

Sample Solution:

Python Code:

# Prompt the user to input a comma-separated sequence of words and store it in the variable 'items'.
items = input("Input comma-separated sequence of words")

# Split the input 'items' into a list of words by using the comma as the separator and store it in the 'words' list.
words = [word for word in items.split(",")]

# Convert the 'words' list into a set to remove any duplicate words, then convert it back to a list.
# Sort the resulting list alphabetically and join the words with commas.
# Finally, print the sorted and comma-separated list of unique words.
print(",".join(sorted(list(set(words)))))

Sample Output:

Input comma separated sequence of words red, black, pink, green                                               
 black, green, pink, red
