Which of the following will give "Simon" as output?If str1="John,Simon,Aryan"print(str1[-7:-12])print(str1[-11:-7])print(str1[-11:-6])print(str1[-7:-11])

The correct answer is print(str1[-11:-7]).

Here's why:

Python string slicing works as follows: str[start:end] where start is the index where the slice starts and end is the index where the slice ends. If start is not given, it's assumed to be 0. If end is not given, it's assumed to be the length of the string.

Negative indexing in Python starts from the end of the string. So, str[-1] will give the last character, str[-2] will give the second last character and so on.

In the string "John,Simon,Aryan", "Simon" starts at the 6th position from the end (if we count the comma before it) and ends at the 11th position from the end. So, to get "Simon", we need to start the slice at -11 and end it at -7.

Therefore, print(str1[-11:-7]) will give "Simon" as output.

The other options will not work because they either start or end at the wrong positions. For example, print(str1[-7:-12]) will not work because the start index is greater than the end index in this case. Similarly, print(str1[-11:-6]) will not work because it includes the comma after "Simon". And print(str1[-7:-11]) will not work for the same reason as the first option.
