I am using Ubuntu 12.10 but with Gnome Fallback session rather than Unity. I was testing out Python by creating a little program to notify if the input year was a leap year or not. I found Ninja IDE useful but had to Edit > Preferences and set the Python path to python3 as shown :
Running the file is easy with Ctrl-F6 and the output is shown within the interface.
I needed to use Python3 as the:
name = input("What is your name? ")
print("You entered " + name)
was throwing errors when print the ‘name’ variable.
