Python String | count ()

|

Syntax :

string.count (substring, start =…, end =…)

Parameters:

The count () function has one compulsory and two optional parameters.
Mandatory parameter:
1) substring - string whose count is to be found.

Optional Parameters:
1) start (Optional) - starting index within the string where search starts.
2) end (Optional) - ending index within the string where search ends.

Returned value:
The count () method returns an integer that represents the number of times when a substring occurs in the given string.

Below is the implementation of the count () method in Python without optional parameters:

# Python program to demonstrate usage
# count () method without additional parameters

  
# string to check for entry

string = " geeks for geeks " 

  
# counts how many times the substring occurs
# this string and returns an integer

print (string.count ( "geeks" ))

Output:

 2 

Below is the implementation of the count () method in Python with using optional parameters.

# Python program to demonstrate usage
# count () method using optional parameters

  
# string where the entry will be checked

string = "geeks for geeks"  

 
# counts how many times a substring occurs
# this string is between indices 0 and 5 and returns
# integer

print (string.count ( "geeks" , 0 , 5 ))

 

print (string.count ( "geeks" , 0 , 15 ))
