Final answer:
The output of the code is "look out the windo!now", created by slicing and concatenating parts of the given strings.
Step-by-step explanation:
The output of the code provided will be:
"look out the windo!now"
This is because the slicing operation look[:-1] returns the string "look out the window" excluding the last character which is the exclamation mark. The second slicing operation find[1:] returns the string "now" starting from the second character of the string "snow". Lastly, look[-1] gets the last character of the look string which is the exclamation mark. When these three parts are concatenated, they form "look out the windo!now".
