paging in python shell

[Alex K]

Hello,

Does anyone know if the python shell supports paging or if I should
look into iPython? Thank you so much.

"Paging" is an overloaded term. What do you mean, exactly? Do you mean
something like piping the output into "more"? The Python shell does that
for the "help" command, but maybe you could post a more precise example of
what you want.

Hi Tim,

Yes I mean piping the output into "more" for example.

Why don't you "suck it and see"???

E.g.

C:\junk>copy con demomore.py
for i in range(100):
print 'line', i
^Z
1 file(s) copied.

C:\junk>python demomore.py | more
line 0
line 1
line 2
line 3
line 4

line 51
line 52
line 53
line 54
line 55

Thanks John, but would it be possible to remain in the python interpreter?

Your example uses the OS shell to invoke a pager on the output of the
Python process. The OP was asking about paging *within* the Python
shell.

To my knowledge there's nothing in the default Python shell that
enables what the OP is asking for. There are other Python shells, e.g.
Idle, ipython, or a Python window inside Emacs, that may be better
suited.

Thanks it's good to know. iPyton looks really neat.

Yes, there is. Thanks to Tim Roberts who menctioned that the builtin help
system implements paging internally, I looked at it. It's easy to use (but
maybe too late for the OP):

Let Python determine the best pager available:

import pydoc
pydoc.pager(tex t)

(it may pipe the text into an external program like less or more). Or
explicitely use the builtin pager:

import pydoc
pydoc.ttypager( text)
