if A or a in stri means if A or  a in stri  which is if True or  a in stri  which is always True  and same for each of your if statements   What you wanted to say is if A in stri or a in stri   This is your mistake  Not the only one - you are not really counting vowels  since you only check if string contains them once   The other issue is that your code is far from being the best way of doing it  please see  for example  this  Count vowels from raw input  You ll find a few nice solutions there  which can easily be adopted for your particular case  I think if you go in detail through the first answer  you ll be able to rewrite your code in a correct way

This works for me and also counts the consonants as well  think of it as a bonus  however  if you really don t want the consonant count all you have to do is delete the last for loop and the last variable at the top   Her is the python code   data   input  Please give me a string     data   data lower   vowels     a   e   i   o   u   consonants     b   c   d   f   g   h   j   k   l   m   n   p   q   r   s   t   v   w   x   y   z   vowelCount   0 consonantCount   0   for string in data      for i in vowels          if string    i              vowelCount    1     for i in consonants          if string    i              consonantCount    1  print  Your string contains  s vowels and  s consonants     vowelCount  consonantCount

You could use regex and dict comprehension   import re s    aeiouuaaieeeeeeee    The regex function findall   returns a list containing all matches  Here x is the key and the lenght of the list returned by the regex is the count of each vowel in this string  note that regex will find any character you introduce into the  aeiou  string   foo    x  len re findall f  x    s   for x in  aeiou   print foo    returns     a   3   e   9   i   2   o   1   u   2
