I am trying to reverse a string in python but i cannot include the first letter.
I tried this code: a = "Helloworld" print(a[3:0:-1])
but it doesn't work. I also tried: a = "Helloworld" print(a[3:-1:-1])
It displays nothing when i try this.

Numbers 3 is the end point but starting from end of string. – malikonakci Feb 11 '23 at 17:57

The code you tried doesn't work because the slice a[3:0:-1] starts at index 3 and goes all the way to index 0 (in reverse), but it includes index 0, which is the first letter of the string.
The slice a[3:-1:-1] starts at index 3 and goes to the index before the last one (-1), but in reverse. This would give an empty string because the step value of -1 goes in the opposite direction of the start and end indices.
To reverse the string excluding the first letter, you can slice it like this:
a = "Helloworld"
print(a[1:][::-1])
