question 13
which method is used to convert a string to uppercase?
upper case()
upper()
to_upper()
make_upper()

Explanation:

Step1: Analyze string indexing

In Python, negative indices count from the end of the string. For the string "Hello", the indices are:

Index (positive)	0	1	2	3	4
Index (negative)	-5	-4	-3	-2	-1

Step2: Access the character

When we use my_string[-4], we are accessing the character at the -4th index. From the above mapping, the character at -4th index is "e".

In Python, the method to convert a string to uppercase is upper(). uppercase() is not a valid Python string method. to_upper() and make_upper() are also not standard Python string methods for this purpose.

Answer:

"e"
