count(string, start_position); #start_position - index

In first case start position is 4 so it will be count after the 5th character

In second case start position is 2 so it will be count after the 3rd character

Answer 2

Quoted from
https://www.w3schools.com/JUMP_LINK__&&__python__&&__JUMP_LINK/ref_string_count.asp

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

Syntax:
string.count(value, start, end)"

The method allows optional arguments - a range of indices which specifies from which index and to which index should the argument be counted.

If <start> index is omitted, the counting starts from 0th character.

If <end> index is omitted, the counting runs to the end of the string - minus length of <value>

Thank AJ Understood
means here we used indexing...
