Before continuing with the next two parts, add a function user_input(lo, hi) to your program. It should ask the user for an integer between lo and hi and return the value. Use appropriate error handling and input validation. 


Part 2.  Using python language:
Write a function named how_many(a_list, a_num) that accept a list of numbers and a number as arguments. It returns how many times the number is found in the list. If the number is not in the list, return 0.              For example how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 ) 
returns 2
 
And how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 )
