Count palindromes java - Python Program to Count Palindrome Words in a Sentence

Count palindromes java: Don’t miss the chance of Java programs examples with output pdf free download as it is very essential for all beginners to experienced programmers for cracking the interviews.

Given a sentence/string the task is to count the number of palindromic words in the given string in Python.

Examples:

Example1:

Input:

Given Sentence =madam how are you

Output:

The total number of palindromic words in the given sentence { madam how are you } are 1

Example2:

Input:

Given Sentence = helleh this issi btechgeeksskeeghcetb pyyp

Output:

The total number of palindromic words in the given sentence { helleh this issi btechgeeksskeeghcetb pyyp } are  4

Program to Count Palindrome Words in a Sentence in Python

Below are the ways to Count Palindrome words in the given sentence in Python

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

Method #1: Using For Loop (Static Input)

Approach:

Give the sentence/string as static input and store it in a variable.
Take a variable palcnt which stores the count of palindromic words in the given sentence and initialize its value to 0.
Split the given sentence into a list of words using the built-in function split() and store it in a variable.
Traverse in this list of words using the For loop.
Inside the for loop,Reverse the iterator word using slicing and store it in a variable.
Check if this reverse word is equal to the iterator word(Palindrome Condition) using the If conditional statement.
If it is true then increment the value of palcnt by 1.
Print the palcnt value.
The Exit of the Program.

Below is the implementation:

# Give the sentence/string as static input and store it in a variable.
gvnsentence ="helleh this issi btechgeeksskeeghcetb pyyp"
# Take a variable palcnt which stores the count of palindromic words
# in the given sentence and initialize its value to 0.
palcnt = 0
# Split the given sentence into a list of words using
# the built-in function split() and store it in a variable.
sentcewords = gvnsentence.split()
# Traverse in this list of words using the For loop.
for itrword in sentcewords:
    # Inside the for loop,Reverse the iterator word
    # using slicing and store it in a variable.
    reveword = itrword[::-1]
    # Check if this reverse word is equal to the
    # iterator word(Palindrome Condition) using the If conditional statement.
    if(reveword == itrword):
        # If it is true then increment the value of palcnt by 1.
        palcnt = palcnt+1


# Print the palcnt value.
print(
    'The total number of palindromic words in the given sentence {', gvnsentence, '} are ', palcnt)

Output:

The total number of palindromic words in the given sentence { helleh this issi btechgeeksskeeghcetb pyyp } are  4

Method #2: Using For Loop (User Input)

Approach:

Give the sentence/string as user input using the input() function and store it in a variable.
Take a variable palcnt which stores the count of palindromic words in the given sentence and initialize its value to 0.
Split the given sentence into a list of words using the built-in function split() and store it in a variable.
Traverse in this list of words using the For loop.
Inside the for loop,Reverse the iterator word using slicing and store it in a variable.
Check if this reverse word is equal to the iterator word(Palindrome Condition) using the If conditional statement.
If it is true then increment the value of palcnt by 1.
Print the palcnt value.
The Exit of the Program.

Below is the implementation:

# Give the sentence/string as user input using the input() function and store it in a variable.
gvnsentence = input('Enter some random sentence =')
# Take a variable palcnt which stores the count of palindromic words
# in the given sentence and initialize its value to 0.
palcnt = 0
# Split the given sentence into a list of words using
# the built-in function split() and store it in a variable.
sentcewords = gvnsentence.split()
# Traverse in this list of words using the For loop.
for itrword in sentcewords:
    # Inside the for loop,Reverse the iterator word
    # using slicing and store it in a variable.
    reveword = itrword[::-1]
    # Check if this reverse word is equal to the
    # iterator word(Palindrome Condition) using the If conditional statement.
    if(reveword == itrword):
        # If it is true then increment the value of palcnt by 1.
        palcnt = palcnt+1


# Print the palcnt value.
print(
    'The total number of palindromic words in the given sentence {', gvnsentence, '} are ', palcnt)

Output:

Enter some random sentence =madam how are you
The total number of palindromic words in the given sentence { madam how are you } are 1
