Python - String Method - count() Tutorial

 It will return the number of occurrences of a substring in the given string. It is case sensitive

Syntax-

String.count(value, start, end)

#String- Value from where the substring needs to be searched
#value - It is a substring that needs to be searched in the given String.
#start - (Optional) It is a position to start the search, by default is 0
#end   - (Optional) It is a position to end search, 
by default is the end of the string

Example-  

str1 = "Hello Python, Hello Fresherbell, Hello"
print(str1.count("Hello"))
print(str1.count('Hello',6,26))
print(str1.count("hello"))

Output-

3
1
0

In the above program,

Line 2- "Hello" is searched in whole string str1, and return count 3

Line 3- "Hello" is searched in string str1 index from 6 to 26, and return count 1

Line 4- "hello" is searched in whole string str1, and return count 0. because the count function will perform a case-sensitive search in whole string.
