Python calculates the number of times an element appears in a list

Define a list and calculate the number of times an element appears in the list.

For example:

enter : lst = [15, 6, 7, 10, 12, 20, 10, 28, 10]

       x = 10

Output : 3

Example 1

def countX(lst, x):
    count = 0
    for ele in lst:
        if (ele == x):
            count = count + 1
    return count
 
lst = [8, 6, 8, 10, 8, 20, 10, 8, 8]
x = 8
print(countX(lst, x))

The output results of the above example are:

5

Example 2

Use the count() method

def countX(lst, x):
    return (x)
 
lst = [8, 6, 8, 10, 8, 20, 10, 8, 8]
x = 8
print(countX(lst, x))

The output results of the above example are:

5
