Why this code is giving output as none. I was trying to get the reversed output

Why the following code is giving me output as none. Basically, I attempt to get the output as Lastname Firstname. So I used split() so that it will return me the list and then I tried to reverse the list using reverse(). Though I'm getting output as none.

CODE:

fn="FirstName LastName".split(" ")
a=fn.reverse()
print(a)
Solution

  • list.reverse() changes list "in-place", so your a variable is None.

    Try:

    fn = "FirstName LastName".split(" ")
fn.reverse()
print(" ".join(fn))

    Prints:

    LastName FirstName
