STEP 5 While that’s very interesting, it’s not particularly exciting.
Instead, try this:
print(“Hello everyone!”)
Just enter it into the IDLE as you’ve done in the previous steps.
STEP 7 You may have noticed the colour coding within the
Python IDLE. The colours represent different elements
of Python code. They are:
Black – Data and Variables
Green – Strings
Purple – Functions
Orange – Commands
Blue – User Functions
Dark Red – Comments
Light Red – Error Messages
STEP 6 This is a little more like it, since you’ve just produced
your first bit of code. The Print command is fairly
self-explanatory, it prints things. Python 3 requires the brackets as well
as quote marks in order to output content to the screen, in this case the
Hello everyone! bit.
STEP 8 The Python IDLE is a configurable environment. If you
don’t like the way the colours are represented, then
you can always change them via Options > Configure IDLE and clicking
on the Highlighting tab. However, we don’t recommend that as you
won’t be seeing the same as our screenshots.
STEP 10 The Python IDLE is a powerful interface, and one that’s
actually been written in Python using one of the available
GUI toolkits. If you want to know the many ins and outs for the Shell, we
recommend you take a few moments to view http://www.docs.python.org/3/
library/idle.html, which details many of the IDLE’s features.
STEP 9 Just like most programs available, regardless of the
operating system, there are numerous shortcut keys
available. We don’t have room for them all here but within the Options



Configure IDLE and under the Keys tab, you can see a list of the
current bindings.
