Python String Count() Method

It returns the number of occurences of substring in the specified range. It takes three parameters, first is a substring, second a start index and third is last index of the range. Start and end both are optional whereas substring is required.

Signature

Parameters

sub (required)
start (optional)
end (optional)

Return Type

It returns number of occurrences of substring in the range.

Let's see some examples to understand the count() method.

Python String Count() Method Example 1

# Python count() function example
# Variable declaration
str = "Hello Javatpoint"
str2 = str.count('t')
# Displaying result
print("occurences:", str2)

Output:

occurences: 2

Python String Count() Method Example 2

# Python count() function example
# Variable declaration
str = "ab bc ca de ed ad da ab bc ca"
oc = str.count('a')
# Displaying result
print("occurences:", oc)

Here, we are passing second parameter (start index).

Python String Count() Method Example 3

# Python count() function example
# Variable declaration
str = "ab bc ca de ed ad da ab bc ca"
oc = str.count('a', 3)
# Displaying result
print("occurences:", oc)

Output:

occurences: 5

The below example is using all three parameters and returning result from the specified range.

Python String Count() Method Example 4

# Python count() function example
# Variable declaration
str = "ab bc ca de ed ad da ab bc ca"
oc = str.count('a', 3, 8)
# Displaying result
print("occurences:", oc)

Output:

occurences: 1

It can count non-alphabet chars also, see the below example.

Python String Count() Method Example 5

# Python count() function example
# Variable declaration
str = "ab bc ca de ed ad da ab bc ca 12 23 35 62"
oc = str.count('2')
# Displaying result
print("occurences:", oc)

Output:
