Python Error

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))

The terminal response to my input "What is your name?" 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

If running Python 2, when using input() the received data is interpreted. To work around this, wrap quotes around your input "j". You could also change to raw_input() which casts the data as a string.

Otherwise, run Python3 where input() assumes data is a string.

Awesome thank you ! Do you have any how to install Python 3.5 on Ubuntu anyways?

Python 3.5 will be harder to get as it's not in the distribution libraries for Ubuntu yet. Unless there is a screaming need for 3.5, Python 3.4 will work fine (it's what i run).

$ sudo apt-get install python3

If you insist on 3.5, check this links:
