How to write a python program to count vowels, consonant, digits and special characters in string.

A string and its job are to count the vowels, consonants, numbers, and special characters in the string. Special characters also contain spaces using Python.

Examples: 

Input : str = "geeks for geeks121"
Output : Vowels: 5
         Consonant: 8
         Digit: 3
         Special Character: 2

Input : str = " A1 B@ d  adc"
Output : Vowels: 2
         Consonant: 4
         Digit: 1
         Special Character: 6

Program:

# Python3 Program to count vowels,
# consonant, digits and special
# character in a given string.

# Function to count number of vowels,
# consonant, digits and special
# character in a string.
def countCharacterType(str):

	# Declare the variable vowels,
	# consonant, digit and special
	# characters
	vowels = 0
	consonant = 0
	specialChar = 0
	digit = 0

	# str.length() function to count
	# number of character in given string.
	for i in range(0, len(str)):
		
		ch = str[i]

		if ( (ch >= 'a' and ch <= 'z') or
			(ch >= 'A' and ch <= 'Z') ):

			# To handle upper case letters
			ch = ch.lower()

			if (ch == 'a' or ch == 'e' or ch == 'i'
						or ch == 'o' or ch == 'u'):
				vowels += 1
			else:
				consonant += 1
		
		elif (ch >= '0' and ch <= '9'):
			digit += 1
		else:
			specialChar += 1
	
	print("Vowels:", vowels)
	print("Consonant:", consonant)
	print("Digit:", digit)
	print("Special Character:", specialChar)


# Driver function.
str = "geeks for geeks121"
countCharacterType(str)
