Letter count

Save all functions into the same file named count.py.

1. Write the function count_up_low() that takes a text (string), and returns two intergers corresponding to the number of uppercase and lowercase letters in the text.

   See the following examples:

   >>> count_up_low('ATENEA is the UPC Virtual Campus')
   (11, 16)
   >>> count_up_low("Barcelona, Paris, London ... I have to choose one.")
   (4, 32)
       
   

   Note

   More tests are provided in the count1.txt file.

2. Write the function vowels_perc() that takes a text (string), and returns the percentage of vowels with respect to the total number of characters in the text.

   See the following examples:

   >>> round (vowels_perc ('Well done is better than well said'), 2)
   29.41
   >>> round (vowels_perc ("Once you choose hope, anything’s possible"), 2)
   34.15
   >>> round (vowels_perc ("If you have no critics you'll likely have no success"), 2)
   32.69
   

   Note

   More tests are provided in the count2.txt file.
