Interactive Edit

If you like to typ it into the interactive environment, you have to start it with
python
and then you type in:
>>> print('Hello World!')

>>> print('Hello World!')
Hello World!

If you have Python 2.X, you type:

>>> print 'Hello World!'

#!/usr/bin/env python
 
print 'Hello World!'

If you have Python 3.X, you must type in:

#!/usr/bin/env python
 
print('Hello World!')
