2.1.2 Interactive Mode
When commands are read from a tty, the interpreter is said to be in interactive mode. In this mode it prompts for the next command with the primary prompt, usually three greater-than signs (‘>>> ’); for continuation lines it prompts with the secondary prompt, by default three dots (‘... ’). The interpreter prints a welcome message stating its version number and a copyright notice before printing the first prompt:
python Python 2.5 (r25:51908, Nov 18 2006, 11:52:11) Type "help", "copyright", "credits" or "license" for more information. >>>
Continuation lines are needed when entering a multi-line construct.
As an example, take a look at this
>>> the_world_is_flat = 1 >>> if the_world_is_flat: ... print "Be careful not to fall off!" ... Be careful not to fall off!
