The get() function tried to retrieve the value of key 9.But, as this key value was not in the dictionary, the get() function returned the default value i.e. When the user entered the string as input, it passed through the for loop statement. Approach. Given a string of length N of lowercase characters containing 0 or more vowels, the task is to find the count of vowels that occurred in all the substrings of the given string. Step 2- Take input of number whose occurrence has to be checked in the list Auxiliary Space: O(n), where n is the length of the string since the function is calling itself n times. #Method 1: Using for loop in a given or entered text file by user at run-time. # make it suitable for caseless comparisions Python Program to Count Vowels in a String Example 1. Next, it counts the total number of vowels and consonants in this string using For Loop..
