You are missing how to use IDLE. It has two kinds of windows: 
interactive Shell and Edit windows. The shell more or less emulates the 
interactive interpreter, running one statement at a time. You can put 
the cursor on a previous statement and hit return to make it the current 
statement, where you can edit it. You edit normal multi-statement code 
in edit windows, hit F5 to run, edit, run, edit, run.
