I don't understand..? I used the command "python hello.py" and the response was: python: can't open file 'hello.py': [Errno 2] No such file or directory

I'd recommend taking at look at this Console Foundations video. Jim explains how to move around the file system, which you'll need to know in order to navigate to your Python file.

If you're unable to view the video, please let me know and I'll try explaining the process.

Awesome thanks! Helps alot. I ended up haing the cd correct, but I was typing in cd python/ instead of cd Python/ .

In any case the program doesn't seem to be working properly. The terminal response to my input is:

Traceback (most recent call last): File "lumberjack.py", line 1, in <module> name = input("What's your name? ") File "<string>", line 1, in <module> NameError: name 'j' is not defined

my code is 

name = input("What's your name? ")

if name == "Jake":
    print("{} is a lumberjack and he is OK!".format(name))
else:
    print(" {} sleeps all day and {} works all day!".format(name, name))

Hey Jake,

Did some snooping around. According to this thread, this is a Python 2 issue.

Change your code to reflect this and it should work:

name = raw_input("What's your name? ")

If you also have the latest version of Python installed, type python3 hello.py into Terminal instead and input() should work at intended.

Hey Jake,

Do you know how to open the terminal on Ubuntu?

Yes, but "python hello.py" brings me: python: can't open file 'hello.py': [Errno 2] No such file or directory

If you're in the working directory of the file hello.py in Terminal, then type 'python hello.py' and hit enter.
