'Reverse last X characters

strVal = input().strip()
X = int(input())
print(-1:X-1:-1)

The program must accept a string S and an integer X as the input. The program must print the last X characters of S in reverse order as the output. As the Problem is what that it runs some of the string and doesnt run some of string.Could anyone tell me whats wrong in this code..did I miss something?

Examples:

For String: baseBall, and input: 4, Output = llab
For String: olympics, and input: 7, Output = scipmyl

python

Solution 1:^[1]

print(strVal[-1:-1-X:-1])

You need to print the slice of strVal. Not just the indexes.

I also changed the indexes to get the right result.

Solution 2:^[2]

print(strVal[-X:][::-1])

First we are getting the last X characters in reverse order, then we are reversing the required part. This is better than understanding indexing for beginners.
