Python program to convert vowel to uppercase character

Python program to convert vowel to uppercase in string

by

In this tutorial, we are going to learn writing python program to convert vowels (‘a’, ‘e’, ‘i’, ‘o’, ‘u’) with their respective uppercase.

Problem Statement

For any input as a string from the user, we have to convert all the vowels present in the string with their respective uppercases.

For example:

Case1: If the user is given an input ‘python’

          Then, the output must be ‘pythOn’.

          The vowel present in the string is ‘o’ which get converted into ‘O’.

Case2: If the user is given an input ‘program’

          Then, the output must be ‘prOgrAm’.

          The vowels present in the string are ‘o’ and ‘a’ which get converted into ‘O’ and ‘A’.

Our logic to convert vowel to uppercase character

  • Our program takes a string input from the user and then iterates through each character of the string using for loop in python to check if any vowel is present in the string.
  • If any vowel is found then it gets replaced using the ‘isupper()’ function. And the output will be generated and printed as a result.

Algorithm to convert vowel to uppercase character

Step1:  Start

Step2:   Take a string as an input from the user.

Step3: Create an empty string, as result = “ ”

Step4:  Use for loop to iterate through the string.

Step5: if vowel found:

                              i = i.uppercase()                   

result+=i ( concatenate the characters of string)

Step6:  Stop

Python code to convert vowel to uppercase character in String

Output:

Explanation:

In this case, the input string ‘Quescol’ contains three vowels ‘u’, ‘e’, and ‘o’, which gets converted into ‘U’, ‘E’, and ‘O’ and replaced with the same.
