The syntax of count() method is:
string.count(substring, start=..., end=...)
count() Parameters
count()
method only requires a single parameter for execution. However, it also has two optional parameters:
substring
- string whose count is to be found.
start (Optional) -
starting index within the string where search starts.
end (Optional) -
ending index within the string where search ends.
Note: Index in Python starts from 0, not 1.
count() Return Value
count()
method returns the number of occurrences of the substring in the given string.
Example 1:
Count number of occurrences of a given substring
# define string
string = "Python is awesome, isn't it?"
substring = "is"
count = string.count(substring)
# print count
print("The count is:", count)
Run Code
Output:
The count is: 2
Example 2:
Count number of occurrences of a given substring using start and end
# define string
string = "Python is awesome, isn't it?"
substring = "i"
# count after first 'i' and before the last 'i'
count = string.count(substring, 8, 25)
# print count
print("The count is:", count)
Run Code
Output
The count is: 1
Here, the counting starts after the first i has been encountered, i.e. 7th index position.
And, it ends before the last i, i.e. 25th index position.
