11. Write a Python function to check whether a number is in a given range. 12. Write a Python function that accepts a string and calculate the number of upper case letters and lower case letters Sample String : "The quick Brow Fox' Expected Output: No. of Upper case characters: 3 No. of Lower case Characters : 12 13. Write a Python function to check whether a number is perfect or not. Acurding to Wikipedia: In number theory, a perfect number is a positive integer that is equal to the sumof its proper positive divisors, that is the sum of its positive divisors excluding the number itself (also known as its aliquot sum). Equivalently, a perfect number is a number that is half the sum of all of its positive divisors (induding itself). Example: The first perfect number is 6, because 1, 2, and 3 are its proper positive divisors, and 1 + 2+3= 6. Equivalently, the number 6 is equal to half the sum of all its positive divisors (1 +2+3 +6)/2= 6. The next perfect number is 28 = 1 +2 +4 +7 +14. This is followed by the perfect numbers 496 and 8128. 14. Write a Python function that checks whether a passed string is palindrome or not. Note: A palindrome is a word, phrase, or sequence that reads the same backward as forward, eg., mudam or nurses run 15. Write a Python program to access a function inside a function 16. Write a recursive function to calculate the sum of numbers from 0 to 10
