  1. Scan string str from 0 to length-1.
  2. check one character at a time on the basis of ASCII values. if(str[i] >= 65 and str[i] <=90), then it is uppercase letter, if(str[i] >= 97 and str[i] <=122), then it is lowercase letter, if(str[i] >= 48 and str[i] <=57), then it is number,
  3. Print all the counters.

How do you count the number of numbers in a string in python?

How do you count the number of vowels and consonants in a string in python?

Algorithm

  1. Define a string.
  2. Convert the string to lower case so that comparisons can be reduced.

  4. If any character lies between ‘a’ and ‘z’ except vowels, then increment the count for ccount by 1.
  5. Print both the counts.
