Python Count String Method
In this Python tutorial, we will look at how to use the Python count string method with our Python strings. The count string method enables us to search a string for occurrences. The count string method takes three arguments first one which are required searches a string for depicted occurrence. The other two arguments define a starting point and ending point for the search. The count string method will return the number occurrences an integer.

Python Count String Method Syntax
'string'.count('occurrence', index starting point, index stopping point)

Occurrence - Must be a string
Index Starting Point - This is an optional argument. Default is 0 and must be present if the index stopping point is present.
Index Stopping Point - This is an optional argument. Default is the end of the string object.
Examples of the Python Count String Method
#Example 1:
a = 'This is a string'

#Example 2:
a.count('s')
3

#Example 3:
a.count('s', 2, 10)
2

#Example 4:
a.count('s', 0, 10)
2

#Example 5:
a.count('s', 0)
3
Examples Explained

Example 1:

a = 'This is a string' - We create a new string object and give it the variable of 'a' to represent the string object.

Example 2:

a.count('s')- We call our string object via the variable 'a' and call the count string method on our string object and we add an occurrence argument of 's'. So the count string method to search our whole string object for the letter s.

3 - We are returned an integer of 3 indicating that the count string method found three 's' in our string object.
Example 3:

a.count('s', 2, 10)- We call our string via the variable 'a' and call the count string method on our string object and we add an occurrence argument of 's' again but this time we add a starting point of the number 2 index location and a ending point of the 10 index location. The count string method will start at 2 index spot(third spot in) and end at the 10 index spot(11th spot in from the left).

2 - We are return an integer of 2 which the count string method only found two occurrences in our string object.

Example 4:

a.count('s', 0, 10)- We call our string via the variable 'a' and call the count string method on our string object. We add an occurrence argument of 's'. This time we add a starting point of '0' to signify the start of the string. If we have an ending point we need to add a starting point so if you want to start at the beginning of the string we need to add '0'. We then add 10 as the ending index.

2 - We are returned an integer value of '2' which indicates that the count string method only found two occurrences in our string object.
Example 5:

a.count('s', 0) - In this example, we call our string method via our variable 'a' and call the count string method on our string object. We add an occurrence argument of 's'. We only provide a starting point of 0 which is actually the default starting point in the count string method.

3 - We are returned an integer of 3 because the count string method has found three occurrences.
