mystr="Hello I am kumar gaurav"
print(mystr[0:9:-1])
When I write this inside print() so no any answer is performed, why? Please explain to me why it is happening there. I do not understand this code.

When you use a negative stride the start idx needs to be greater than the end idx. – ggorlen Jan 01 '21 at 16:53

according to this [start, stop, step] you slicing your string from 0 indexes to 9 indexes but through the step of -1(step means Jump -1 step). so this means when start is 0 you told to go back one step and there's no character behind o indexes('H').
use this
print(mystr[0:9][::-1]) // to reverse
