Can anyone help with this python question. Been working on it for over an hr.?

Use the variables k , d , and s so that they can read three different values from standard input--an integer, a double, and a string respectively. On one line, print these variables in reverse order with exactly one space in between each. On a second line, print them in the original order with one space in between them.

I keep writing this but doesnt work: print("s", str("d"), str("k"))

print("k", str("d"), str("s"))
