Python Program to Print each Word of a Sentence along with Number of Vowels in each Word

Given a sentence, the task is to print each word of a Sentence along with the number of vowels in each word.

Examples:

Example1:

Input:

Given word ='Hello this is BTechgeeks'

Output:

The total number of vowels in the given word { hello } is 2
The total number of vowels in the given word { this } is 1
The total number of vowels in the given word { is } is 1
The total number of vowels in the given word { btechgeeks } is 3

Example2:

Input:

Given word = 'good morning this is btechgeeks python coding platform'

Output:

The total number of vowels in the given word { good } is 2
The total number of vowels in the given word { morning } is 2
The total number of vowels in the given word { this } is 1
The total number of vowels in the given word { is } is 1
The total number of vowels in the given word { btechgeeks } is 3
The total number of vowels in the given word { python } is 1
The total number of vowels in the given word { coding } is 2
The total number of vowels in the given word { platform } is 2

Program to Print each Word of a Sentence along with the Number of Vowels in each Word in Python

Below are the ways to print each word of a Sentence along with the number of vowels in each word.

• Using For loop(Static Input)
• Using For loop(User Input)

Practice Java programming from home without using any fancy software just by tapping on this Simple Java Programs for Beginners tutorial.

Method #1: Using For Loop (Static Input)

Approach:

• Give the sentence as static input and store it in a variable.
• Convert the given string/sentence to lowercase using the lower() function.
• To break words from a sentence, use the string.split() method.
• The words will be separated and kept in a list named ‘stringwords’
• Create a list called vowelchars, which will hold all of the vowels in the English alphabet.
• Iterate through the list of words and set up a counter to count the number of vowels in each one.
• Start a nested loop that iterates throughout the word in question, checking whether any of the characters are vowels.
• Increase the counter if a character is a vowel.
• Print the current iteration’s word and the value of the counter corresponding with it (which contains the sentence’s number of vowels).
• The Exit of the program.

Below is the implementation:

# Give the sentence as static input and store it in a variable.
givnstrng = 'Hello this is BTechgeeks'
# Convert the given string/sentence to lowercase using the lower() function.
givnstrng = givnstrng.lower()
# To break words from a sentence, use the string.split() method.
# The words will be separated and kept in a list named ‘wordslst'
wordslst = givnstrng.split()
# Create a list called vowelchars, which will hold all of the vowels in the English alphabet.
vowelchars = ['a', 'e', 'i', 'o', 'u']
# Iterate through the list of words and set up a counter to count
# the number of vowels in each one.
for gvnword in wordslst:
    cntvowel = 0
    # Start a nested loop that iterates throughout the word in question,
    # checking whether any of the characters are vowels.
    for m in gvnword:
        # Increase the counter if a character is a vowel.
        if m in vowelchars:
            cntvowel = cntvowel+1
    # Print the current iteration's word and the value
    # of the counter corresponding with it
    # (which contains the sentence's number of vowels).
    print(
        'The total number of vowels in the given word {', gvnword, '} is', cntvowel)

Output:

The total number of vowels in the given word { hello } is 2
The total number of vowels in the given word { this } is 1
The total number of vowels in the given word { is } is 1
The total number of vowels in the given word { btechgeeks } is 3

Method #2: Using For Loop (User Input)

Approach:

• Give the sentence as user input using input() and store it in a variable.
• Convert the given string/sentence to lowercase using the lower() function.
• To break words from a sentence, use the string.split() method.
• The words will be separated and kept in a list named ‘stringwords’
• Create a list called vowelchars, which will hold all of the vowels in the English alphabet.
• Iterate through the list of words and set up a counter to count the number of vowels in each one.
• Start a nested loop that iterates throughout the word in question, checking whether any of the characters are vowels.
• Increase the counter if a character is a vowel.
• Print the current iteration’s word and the value of the counter corresponding with it (which contains the sentence’s number of vowels).
• The Exit of the program.

Below is the implementation:

# Give the sentence as user input using input() and store it in a variable.
givnstrng = input('Enter some random sentence = ')
# Convert the given string/sentence to lowercase using the lower() function.
givnstrng = givnstrng.lower()
# To break words from a sentence, use the string.split() method.
# The words will be separated and kept in a list named ‘wordslst'
wordslst = givnstrng.split()
# Create a list called vowelchars, which will hold all of the vowels in the English alphabet.
vowelchars = ['a', 'e', 'i', 'o', 'u']
# Iterate through the list of words and set up a counter to count
# the number of vowels in each one.
for gvnword in wordslst:
    cntvowel = 0
    # Start a nested loop that iterates throughout the word in question,
    # checking whether any of the characters are vowels.
    for m in gvnword:
        # Increase the counter if a character is a vowel.
        if m in vowelchars:
            cntvowel = cntvowel+1
    # Print the current iteration's word and the value
    # of the counter corresponding with it
    # (which contains the sentence's number of vowels).
    print(
        'The total number of vowels in the given word {', gvnword, '} is', cntvowel)

Output:

Enter some random sentence = good morning this is btechgeeks python coding platform
The total number of vowels in the given word { good } is 2
The total number of vowels in the given word { morning } is 2
The total number of vowels in the given word { this } is 1
The total number of vowels in the given word { is } is 1
The total number of vowels in the given word { btechgeeks } is 3
The total number of vowels in the given word { python } is 1
The total number of vowels in the given word { coding } is 2
The total number of vowels in the given word { platform } is 2
