Unable to understand Python negative string slicing

Question

Why doesn't it reverse the string when we put some numbers in start and stop parameters?

Example:

name = "i am a student"
print(name[0:14:-1])

does not reverse the string

what is your expected output? Are you intended to do partial reverse? — Tasnuva, Sep 07 '20 at 04:05

In this line name[0:14:-1] in 14th position there is nothing in the string. slice notation is:

[ <first element to include> : <first element to exclude> : <step> ]

If you want to include the first element when reversing a list, leave the middle element empty, like this:

name = "i am a student"
s = name[::-1]
print(s) # output tneduts a ma i

please add your expected output with the post.
