Python | Count occurrences of an element in a list

Given a list in Python and a number x, count number of occurrences of x in the given list.
Examples: 
 

Input : lst = [15, 6, 7, 10, 12, 20, 10, 28, 10]
         x = 10
Output : 3 
10 appears three times in given list.

Input : lst = [8, 6, 8, 10, 8, 20, 10, 8, 8]
        x = 16
Output : 0

Method 1 (Simple approach) 
We keep a counter that keeps on increasing if the required element is found in the list.
 

Output:
8 has occurred 5 times

Method 2 (Using count()) 
The idea is to use list method count() to count number of occurrences. 
 

Output:
8 has occurred 5 times 

Method 2 (Using Counter()) 
Counter method returns a dictionary with occurrences of all elements as a key-value pair, where key is the element and value is the number of times that element has occurred. 
 

Output:
3 has occurred 2 times
