How Can I Count Substring Occurrences in Python?

Counting Substring Occurrences in Python

Determining the frequency of a particular substring within a larger string is a common task in programming. In Python, you can efficiently achieve this using the count() method.

Method:

The string.count(substring) method returns the total number of non-overlapping occurrences of a specified substring within a string. For example:

>>> 'foo bar foo'.count('foo')
2

Non-Overlapping Occurrences:

The count() method considers only the first occurrence of the substring in each specific location. It does not account for overlapping occurrences.

Alternative for Overlapping Occurrences:

If you need to count overlapping occurrences, there are more advanced methods or libraries that can handle this task. Refer to additional resources or consider alternative approaches for capturing overlapping occurrences.
