I guess you're trying to run the script within the Python REPL, right?

You can tell the difference by looking at the prompt

  • >>> you're at Python REPL
  • treehouse:~/workspace$ you're at the Linux command line

The command you're using python lumberjack.py will only work at the command line.

You should first exit the Python REPL by typing exit(), now back into the Command line, you can enter the python lumberjack.py

Hope that helps

check your lumberjack.py file, if it's empty, then of course nothing happens. If you want something happens like print out hello world, you need to actually add the code to lumberjack.py 

print("hello world")

and save the file; also please notice that during the lecture, Kenneth's lumberjack.py also has some codes on it that asks for user to input his name.
