def countCharacterType(str): 

vowels = 0

for i in range(0, len(str)): 

ch = str[i] 

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

(ch >= 'A' and ch <= 'Z') ):

or ch == 'o' or ch == 'u'): 

vowels += 1

else: 

consonant += 1

elif (ch >= '0' and ch <= '9'):

print("Vowels:", vowels) 

print("Consonant:", consonant) 

print("Digit:", digit) 

print("Special Character:", specialChar) 

# Driver function. 

f=open("data.txt")

str=f.read()
