Given a string and the task is to find the longest word from a given sentence.
split() method:
The split() method in Python divides a string into a list of strings by breaking the string with the specified separator.
Examples:
Example1:
Input:
Given String = "Hello this is btechgeeks"
Output:
The Longest Word in the above given sentence = btechgeeks The length of the longest word = 10
Example2:
Input:
Given String = "Goodmorning this is btechgeeks"
Output:
The Longest Word in the above given sentence = Goodmorning The length of the longest word = 11
Program to Find Longest Word from Sentence
Below are the ways to find the longest word from a given sentence.
Method #1: Using Built-in Functions (Static Input)
Approach:
- Give the string as static input and store it in a variable.
- Split the given string into a list of words using the split() function and store it in another variable say “wrd_lst”.
- Get the longest word from a given sentence using max(), key functions, and store it in another variable.
- Calculate the length of the above-obtained longest word using the len() function and store it in another variable.
- Print the longest word in the above-given sentence.
- Print the above-obtained length of the longest word.
- The Exit of the Program.
Below is the implementation:
# Give the string as static input and store it in a variable.
Gvn_str = "Hello this is btechgeeks"
# Split the given string into a list of words using the split() function and
# store it in another variable say "wrd_lst".
wrd_lst = Gvn_str.split()
# Get the longest word from a given sentence using max(), key functions, and
# store it in another variable.
longst_wrd = max(wrd_lst, key=len)
# Calculate the length of the above-obtained longest word using the len() function
# and store it in another variable.
len_longst_wrd = len(longst_wrd)
# Print the longest word in the above-given sentence.
print("The Longest Word in the above given sentence = ", longst_wrd)
# Print the above-obtained length of the longest word.
print("The length of the longest word = ", len_longst_wrd)
Output:
The Longest Word in the above given sentence = btechgeeks The length of the longest word = 10
Method #2: Using Built-in Functions (User Input)
Approach:
- Give the string as user input using the input() function and store it in a variable.
- Split the given string into a list of words using the split() function and store it in another variable say “wrd_lst”.
- Get the longest word from a given sentence using max(), key functions, and store it in another variable.
- Calculate the length of the above-obtained longest word using the len() function and store it in another variable.
- Print the longest word in the above-given sentence.
- Print the above-obtained length of the longest word.
- The Exit of the Program.
Below is the implementation:
# Give the string as user input using the input() function and store it in a variable.
Gvn_str = input("Enter some random sentence = ")
# Split the given string into a list of words using the split() function and
# store it in another variable say "wrd_lst".
wrd_lst = Gvn_str.split()
# Get the longest word from a given sentence using max(), key functions, and
# store it in another variable.
longst_wrd = max(wrd_lst, key=len)
# Calculate the length of the above-obtained longest word using the len() function
# and store it in another variable.
len_longst_wrd = len(longst_wrd)
# Print the longest word in the above-given sentence.
print("The Longest Word in the above given sentence = ", longst_wrd)
# Print the above-obtained length of the longest word.
print("The length of the longest word = ", len_longst_wrd)
Output:
Enter some random sentence = Goodmorning this is btechgeeks The Longest Word in the above given sentence = Goodmorning The length of the longest word = 11
