Problem statement
Python program to accept a string from the user, divide the string into words and display the words of string from longest to shortest.
Video Tutorial
Steps
First, accept a string from the user using the input statement and store it into a string variable. say str1 in this case.
Divide the string into words using the split() function, store the result that is a list of words into a words list.
Create an empty list to store the word and its length as a tuple. say t in this case.
Use for loop and get one word from the words list in each iteration.
Append the tuple (length of word and word) into list t.
Once all words are appended to the list t, sort the list t in reverse order.
As we need to sort the words from the longest to shortest sort in reverse order.
Next, create a res list to store the words from the list t, use for loop to get the elements of t. The element of t is actually a tuple, hence use multiple assignments in for loop.
Finally, append the word to the res list. Once all words are appended display the res list.
Solution: Program to display the words of string from longest to shortest
#Suppose you have a string and you want to sort the words of string from longest to shortest:
str1 = input("Enter the string: ")
print ("String is: ", str1)
words = str1.split()
print ("Words in string are: ", words)
t = list()
for word in words:
t.append((len(word), word))
t.sort(reverse=True)
res = list()
for length, word in t:
res.append(word)
print("Words in string sorted from longest to shortest:", res)
Output
Enter the string: HSIT Nidasoshi VTU Belagavi String is: HSIT Nidasoshi VTU Belagavi Words in string are: ['HSIT', 'Nidasoshi', 'VTU', 'Belagavi'] Words in string sorted from longest to shortest: ['Nidasoshi', 'Belagavi', 'HSIT', 'VTU']
