Python program to count number of vowels using sets in given string
Given a string, count the number of vowels present in given string using Sets.
Prerequisite: Sets in Python
Examples:
Input : GeeksforGeeks Output : No. of vowels : 5 Input : Hello World Output : No. of vowels : 3
Approach:
1. Create a set of vowels using set() and initialize a count variable to 0.
2. Traverse through the alphabets in the string and check if the letter in the string is present in set vowel.
3. If it is present, the vowel count is incremented.
Below is the implementation of above approach:
# Python3 code to count vowel in # a string using set # Function to count vowel def vowel_count(str): # Intializing count variable to 0 count = 0 # Creating a set of vowels vowel = set("aeiouAEIOU") # Loop to traverse the alphabet # in the given string for alphabet in str: # If alphabet is present # in set vowel if alphabet in vowel: count = count + 1 print("No. of vowels :", count) # Driver code str = "GeeksforGeeks" # Function Call vowel_count(str) |

Output:
No. of vowels : 5
