Looks like you're trying to run the Python script while inside the Python REPL. No, you can't do that.

First, you have to exit the Python REPL by entering exit(), then you can run the script with python lumberjack.py

You have a space in your first print statement print (name + "is learning python and is a lumberjack") directly after the word print in the if/else block. 

name = input("what is your name? ")

if name == "ABC":
    print(name + "is learning python and is a lumberjack")
else: 
    print(name + "already knows python")

Hey Arun, you exit the REPL with exit(), then you enter REPL again with python command, don't do that, please, that'd only take you back to square one.

  1. exit()
  2. python lumberjack.py

that's all.

You command prompt has to be showing treehouse:~/workspace$, this is the indication that you're not in the Python REPL, then you can run the script by entering python lumberjack.py.
