Python String count() Method

Last Updated : 06 Nov, 2024

The count() method in Python returns the number of times a specified substring appears in a string. It is commonly used in string analysis to quickly check how often certain characters or words appear.

Let’s start with a simple example of using count().

s = "hello world"
res = s.count("o")
print(res)

Output

Explanation: The letter “o” appears twice in the string “hello world”, so count() returns 2.

Syntax of count() Method

string.count(substring, start = 0, end = len(s))

Parameters

substring (required): The substring we want to count within the original string.
start (optional): The index position in the string where the search should begin. Default is 0.
end (optional): The index position in the string where the search should stop. Default is the length of the string (i.e., up to the end).

Return Type

The count() method returns an integer representing the number of times the specified substring appears within the given range of the string.

Example of count() Method

Here are a few examples of count() method for better understanding.

Counting Words in String

s = "Python is fun and Python is powerful."
print(s.count("Python"))

Output

Finding Character Frequency in String

s = "GeeksforGeeks"
print(s.count("e"))

Output

Count Substring Occurrences with Start and End parameter

s = "apple banana apple grape apple"
substring = "apple"

# Using start and end parameters to count occurrences 
# of "apple" within a specific range
res = s.count(substring, 1, 20)  

print(res)

Output

Explanation: We set start=1 and end=20, so count() method will search for “apple” from the beginning up to index 20.
