In this post, we will write a Python program to check whether the entered character is vowel or consonant.
Python Code
In this program, user is asked to input a character. The program checks whether the entered character is equal to the lowercase or uppercase vowels, if it is then the program prints a message saying that the character is a Vowel else it prints that the character is a Consonant.
# taking user input ch = input["Enter a character: "] if[ch=='A' or ch=='a' or ch=='E' or ch =='e' or ch=='I' or ch=='i' or ch=='O' or ch=='o' or ch=='U' or ch=='u']: print[ch, "is a Vowel"] else: print[ch, "is a Consonant"]
Output:

Problem: Write a Python program to count the number of vowels and consonants in a given string. Example: To count the number of vowels and consonants in a string, we iterate using a for loop through each character of the string and check if it matches a vowel. If yes
then, we increment the vowel counter otherwise increment the consonant counter. Output: Enter a string: Pencil Programmer Enter a string: PythonString: Pencil Programmer
Vowels: 5
Consonants: 12
#define all vowels in a list
vowels = ['a', 'e', 'i', 'o', 'u']
#input a string and transform it to lower case
str = input["Enter a string: "].lower[]
#define counter variable for both vowels and consonants
v_ctr = 0
c_ctr = 0
#iterate through the characters of the input string
for x in str:
#if character is in the vowel list,
#update the vowel counter otherwise update consonant counter
if x in vowels:
v_ctr += 1
elif x != ' ':
c_ctr += 1
#output the values of the counters
print["Vowels: ", v_ctr]
print["Consonants: ", c_ctr]
Vowels: 5
Consonants: 12
Vowels: 1
Consonants: 5
In the above program, we have defined all vowels of the English alphabet in a list and use the same to check for vowels in the string.
Inside the
for
loop, we check whether the character [x
] of the string is present in the vowels
list or not.
If yes then it is a vowel, so we increment the vowel counter [v_ctr += 1
] otherwise, we increment the counter of consonants [c_ctr += 1
].
Finally, we output both counter’s values at the end of the program.

In this article, we will discuss the concept of the Python program to count vowels or consonants of the given string
In this post, we are going to learn how to count the vowels and consonants in the given string in Python programming language
Python code to count the vowels and consonants using for loop
The program allows the user to enter a string thereafter It counts the vowels and consonants of the given string using for loop in Python language
Program 1
#Python program to count vowel or consonant of the given string str=input["Please enter a string as you wish: "]; vowels=0 consonants=0 for i in str: if[i == 'a'or i == 'e'or i == 'i'or i == 'o'or i == 'u' or i == 'A'or i == 'E'or i == 'I'or i == 'O'or i == 'U' ]: vowels=vowels+1;#vowel counter is incremented by 1 else: consonants=consonants+1; #consonant counter is incremented by 1 print["The number of vowels:",vowels]; print["\nThe number of consonant:",consonants];
When the above program is executed, it produces the following result
Please enter a string as you wish: python The number of vowels: 1 The number of consonants: 5
Approach
- Declare and initialize two integer counter variable as int vowels=0 and consonants=0;
- The user asked to enter a string to count vowels and consonants
- A for-loop is used to count total vowels and consonants of the given string
- Use an if statement to test vowel if the test expression is true, vowels become vowels + 1[vowels=vowels+1]
- When the if-statement is false, control moves to else part and executes else part statements
- Finally, the program displays the number of vowels and consonants of the given string.

Program 2
#Python program to count vowel or consonant of the given string str=input["Please enter a string as you wish: "]; vowels=0 consonants=0 str.lower[]#call the lower function to avoid upper case letter for i in str: if[i == 'a'or i == 'e'or i == 'i'or i == 'o'or i == 'u' ]: vowels=vowels+1; else: consonants=consonants+1; print["The number of vowels:",vowels]; print["\nThe number of consonant:",consonants];
When the above program is executed, it produces the following result
Please enter a string as you wish: Python language The number of vowels: 5 The number of consonants: 10
Approach
- Declare and initialize two integer counter variable as int vowels=0 and consonants=0;
- The user asked to enter a string to count vowels and consonants
- call the str.lower[] string function to change upper case lettersto lower case letters
- A for-loop is used to count total vowels and consonants of the given string using the vowels and consonants variables
- Use an if statement to test vowel if the test expression is true, vowels become vowels + 1[vowels=vowels+1]
- When the if-statement is false, control moves to else part and executes else part statements
- Finally, the program displays the number of vowels and consonants of the given string.
