Python program to count the number of vowels using set in a given string

We will count the number of vowels using set in a given string. Let’s say we have the following input −

jackofalltrades

The output should be the following, counting the number of vowels −

65

Count the number of vowels using set in a given string

We will count the number of vowels using set in a give string −

Example

def vowelFunc(str):
	c = 0
	# Create a set of vowels
	s="aeiouAEIOU"
	v = set(s)

	# Loop to traverse the alphabet in the given string
	for alpha in str:
		# If alphabet is present
		# in set vowel
		if alpha in v:
			c = c + 1
	print("Count of Vowels = ", c)

# Driver code
str = input("Enter the string = ")
vowelFunc(str)

Output

Enter the string = howareyou
Count of Vowels = 5

Count the number of vowels using set in a given string without using a function

We will count the number of vowels using set without using a function −

Example

# string to be checked
myStr = "masterofnone"
count = 0

print("Our String = ",myStr)

# Vowel Set
vowels = set("aeiouAEIOU")

# Loop through, check and count the vowels
for alpha in myStr:
	if alpha in vowels:
		count += 1
print("Count of Vowels = ",count)

Output

Our String = masterofnone
Count of Vowels = 5
