Q.Identify the correct output of the following code snippet: game="Olympic2024" print(game.index("C")) (A) 0 (B) 6 (C) -1 (D) ValueError

Concept: The str.index() method in Python searches for the first occurrence of a substring and returns its zero-based index position.

Reasoning:

1. The string game = "Olympic2024" has characters indexed from 0 onwards: O(0), l(1), y(2), m(3), p(4), i(5), c(6), 2(7), 0(8), 2(9), 4(10).

2. The method game.index("C") searches for the uppercase letter "C" in the string.

3. The string contains only a lowercase "c" at index 6, not an uppercase "C". …

Why index() behaves this way

The index() method in Python strings searches for the first occurrence of a substring and returns its zero-based position. The crucial detail: if the substring is not found, index() does not return -1 or 0 — it raises a ValueError exception and halts execution.

This is different from the find() method, which returns -1 when the substring is absent. The designers of Python made index() strict: if you ask for the position of something that doesn't exist, that's an error condition worth stopping for.

Step-by-step trace

1. Initialize the string

   game = "Olympic2024" creates a string with characters at positions:

   Position	0	1	2	3	4	5	6	7	8	9	10
   Character	O	l	y	m	p	i	c	2	0	2	4

2. Search for "C"

   The method game.index("C") looks for the uppercase letter "C" in the string.

3. Case-sensitive comparison

   Python strings are case-sensitive. The string contains a lowercase "c" at position 6, but "C" (uppercase) does not appear anywhere.

4. Exception raised

   Because "C" is not found, Python raises:
