Given a string that contains both upper and lower case characters in it. The task is to count number of upper and lower case characters in it without using in-built functions.
Counting the upper and lower case characters of a string can be easily done using
islower() functions, refer this. But doing the same without help of any inbuilt function is quite exciting. Let’s see how this can be done :
Input : Introduction to Python Output : Lower Case characters : 18 Upper case characters : 2 Input : Welcome to GeeksforGeeks Output : Lower Case characters : 19 Upper case characters: 3
Below is the implementation of above idea :
Lower case characters = 27 Upper case characters = 3
Lower case characters: 8 Upper case characters: 3
