Invoking the interpreter without passing a script file as a parameter brings up the following prompt −

$ python
Python 2.4.3 (#1, Nov 11 2010, 13:34:43)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

Type the following text at the Python prompt and press the Enter:

>>> print "Hello, Python!"

Hello, Python!
