Description:

Return the number [count] of vowels in the given string.

We will consider a, e, i, o, u as vowels for this Kata [but not y].

The input string will only consist of lower case letters and/or spaces.

Loop

function getCount[str] {
  let vowelsCount = 0
  const vowels = ["a", "e", "i", "o", "u"]
  for[let char of str] {
      if[vowels.includes[char]] {
          vowelsCount++
      }
  }

  return vowelsCount;
}

RegEx

function getCount[str] {
    return str.match[/[aeiou]/gi].length
}

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

1. Declare and initialize two integer counter variable as int vowels=0 and consonants=0;
2. The user asked to enter a string to count vowels and consonants
3. A for-loop is used to count total vowels and consonants of the given string
4. Use an if statement to test vowel if the test expression is true,  vowels become vowels + 1[vowels=vowels+1]
5. When the if-statement is false, control moves to else part and executes else part statements
6. Finally, the program displays the number of vowels and consonants of the given string.

Python code to count the vowels and consonants using for loop – strlen[] function

The program allows the user to enter a string  thereafter It counts the vowels and consonants of the given string using strlen[] function in Python  language

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

1. Declare and initialize two integer counter variable as int vowels=0 and consonants=0;
2. The user asked to enter a string to count vowels and consonants
3. call the str.lower[] string function to change upper case lettersto lower case letters
4. A for-loop is used to count total vowels and consonants of the given string using the vowels and consonants variables
5. Use an if statement to test vowel if the test expression is true,  vowels become vowels + 1[vowels=vowels+1]
6. When the if-statement is false, control moves to else part and executes else part statements
7. Finally, the program displays the number of vowels and consonants of the given string.

How do you find the number of vowels in Python?

Step 1: Take a string from the user and store it in a variable. Step 2: Initialize a count variable to 0. Step 3: Use a for loop to traverse through the characters in the string. Step 4: Use an if statement to check if the character is a vowel or not and increment the count variable if it is a vowel.

How do you count a number of vowels and consonants in a given string?

Approach:.

Take the string as input..

Take each character from this string to check..

If this character is a vowel, increment the count of vowels..

Else increment the count of consonants..

Print the total count of vowels and consonants in the end..

How do you separate vowels and consonants in a string in python?

def anti_vowel[c]:.

newstr = c..

vowels = ['a', 'e', 'i', 'o', 'u'].

for x in c. lower[]:.

if x in vowels:.

newstr = newstr. replace[x,""].

return newstr..
