Normally, you would just do:
s = s[:-3] + s[-2:]
The s[:-3] gives you a string up to, but not including, the comma you want removed ("this is a string") and the s[-2:] gives you another string starting one character beyond that comma (" a").
Then, joining the two strings together gives you what you were after ("this is a string a").

Is string slicing actually useful in real world applications?
If you are doing lot of text processing, then yes. Here's an example from my usecase. I have markdown files with code snippets starting with $ or >>> etc. I have to post process those files to extract only the command that comes after the prompt. Easiest solution is string slicing, since the length of the prompt is fixed. Also, slicing in Python can be applied to lists, tuples, strings, etc. So, even if you are not doing text processing, you can apply the knowledge elsewhere. More on reddit.com

A couple of variants, using the "delete the last comma" rather than "delete third last character" are:
s[::-1].replace(",","",1)[::-1]
or
''.join(s.rsplit(",", 1))
But these are pretty ugly. Slightly better is:
a, _, b = s.rpartition(",")
s = a + b
This may be the best approach if you don't know the comma's position (except for last comma in string) and effectively need a "replace from right". However Anurag's answer is more pythonic for the "delete third last character".

The step count given by you in s[0:-5:-1] is -1, which means that string slicing will be reverse like 'a','v','i','S'.
But you are starting from s[0] which is "S" and due to the step count -1, it will print the previous character from the string "Siva". But there are no characters before 'S'. That's why it's stopping and only printing 'S'.
If you want the reverse of s = "Siva", then simply write s[::-1].

Slicing is s[start:end:step] so if you want Savi you have to do
s[0] + s[-1:0:-1]
- Start at -1 means start at the end of the string.
- End at 0 means end at the beginning ignoring this first character.
- Step -1 means go reverse one at a time.

The last index of the slice or the number of items to get. Defaults to len(sequence). step · Optional. Extended slice syntax. Step value of the slice. Defaults to 1. The same as selected. O(k) for slice retrieval · O(n) for deletion · O(n+k) for slice assignment · Consider the following ASCII graph showing the contents of the “ABCD” string: >>> +---+---+---+---+ >>> |-4 |-3 |-2 |-1 | <= negative indexes >>> +---+---+---+---+ >>> | A | B | C | D | <= sequence elements >>> +---+---+---+---+ >>> | 0 | 1 | 2 | 3 | <= positive indexes >>> +---+---+---+---+ >>> |<- 0:3:1 ->| <= extent of the slice: "ABCD"[0:3:1] Consider the following example: >>> "ABCD"[0:2] 'AB' It can be read as: get every single one item between indexes 0 and 2 (exclusive).

Im doing an online bootcamp at the moment and they've spent a fair bit of time going over string slicing. I couldnt help but think theres little to no real world uses for this stuff. Am I incorrect? if so what is a reasonable scenario in which you would **need** string slicing?
