In print function you're slicing the string from 1st index to less than 3rd index. But you're using a negative step (which means reverse). So it won't print anything. If you use positive step then it will print el. Here is the corrected code:

print(St[1:3:1])

As you are reversing the string (-1 in the slicing), you should also treat the elements of the string reversed, so 3 comes before 1. Try the following:

print(St[3:1:-1])

I would do it like this:

s = "hello to all my friends in python"
print(s[1,2])
