Write a function called countElements that counts the number
     Write a function called countElements that counts the number of times two elements appear in a list. Your task is to ask the user to enter a list and two elements which they need to count in the list. The list and each of the elements should be inputs to a function called countElements. The function should print the count of the number of times the elements appear in the list.  def countElements(countUst, element1, element2):  Example: if the inputs to the function were (\"t\", \"s\", 7, 7, 2], \"t\", and 7, the function would count the instances of the letter T and the number 7 in the list, and print the number 3. There was one T and two 7\'s.  Name your file Lastname_Firstname.py 
  
  Solution
def countElements(list, ch1, ch2):
 count = 0
 for i in range(0,len(list)):
 if list[i] == ch1:
 count = count + 1
 for i in range(0,len(list)):
 if list[i] == ch2:
 count = count + 1
 return count;
   
print countElements([\"t\",\"s\",7,7,2], \"t\", 7)
Output:
