The python count() method counts the number of occurrences of an element in the list and returns it.

Syntax:

    list.count(x)

The count() method takes a single argument, x, whose count is to be found. The count() method returns the number of occurrences of an element in a list.

Example:

# an example of list.count() method in Python

# declaring a list
website_list = ['google.com','includehelp.com', 'linkedin.com', 'google.com']

# counting the occurrences  of 'google.com'
count = website_list.count('google.com')
print('google.com found',count,'times.')

# counting the occurrences  of 'linkedin.com'
count = website_list.count('linkedin.com')
print('linkedin.com found',count,'times.')

Output

google.com found 2 times.
linkedin.com found 1 times.

The count() method works on tuple as well

Example:

# an example of count() method with tuple in Python

# declaring a tuple
sample_tuple = ((1,3), (2,4), (4,6))

# conting occurrences  of (1,2)
count = sample_tuple.count((1,2))
print('(1,2) found',count,'times.')

# conting occurrences  of (1,3)
count = sample_tuple.count((1,3))
print('(1,3) found',count,'times.')

Output

(1,2) found 0 times.
(1,3) found 1 times.
