Python String count() method

Python String count() method

The string.count() method returns the number of times a specified value appears in the string.

Syntax

string.count(sub[, start[, end]])

Parameter

sub: This parameter represents a substring to be searched.

start: This parameter signifies the position to start the search. By default the value is 0.

end: This parameter signifies the position to end the search. By default the value is the end of the string.

Return

This method returns the number of occurrences of substring sub in string S[start:end].

Example 1

 # Python String program explaining
 # the count() method
 # passing the string
 str = "Heeelo World ";
 print("String value:",str)
 # returning the count of alphabet 'e'
 print ("The count of 'e' in the string is", str.count('e')) 

Output

String value: Heeelo World 
The count of 'e' in the string is 3

Example 2

 # Python String program explaining
 # the count() method
 # passing the string
 str = "This is a python string example";
 # Search starts from sub index 'i'.
 sub = "i";
 print ("str.count(sub, 4, 40) : ", str.count(sub, 4, 40))
 sub = "python";
 print ("str.count(sub) : ", str.count(sub)) 

Output

str.count(sub, 4, 40) :  2
str.count(sub) :  1

Example 3

 # Python String program explaining
 # the count() method
 # string to check the occurence
 string = "Hello world Hello" 
 # counting the occurence of substring in between index 0 and 5 
 print(string.count("Hello", 0, 5)) 
 # counting the occurence of substring in between index 0 and 15
 print(string.count("Hello", 0, 15))
