Python String count() Method - GeeksforGeeks

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)

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

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

• 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).

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

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

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

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

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)

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