# Python code to count the number of occurrences

def countX(lst, x):

count = 0

for ele in lst:

if (ele == x):

count = count + 1

return count

# Driver Code

lst = [2,4,2,7,5 ,3,4,7,2,5]

x = 2

y=3

z=4

a=5

b=7

print('{} has occured {} times'.format(x, countX(lst, x)))

print('{} has occured {} times'.format(x, countX(lst, y)))

print('{} has occured {} times'.format(x, countX(lst, z)))

print('{} has occured {} times'.format(x, countX(lst, a)))

print('{} has occured {} times'.format(x, countX(lst, b)))
