[IronPython] Newbie question about 'import'

Depends what you want to find out. The easy way is using dir and __doc__:

import sys

dir(obj) lists attributes available on the given object
dir() lists contents of global namespace

__doc__ provides documentation, if any:

>>> import first
>>> first.add.__doc__
'add(a, b) -> returns a + b'

However, IronPython only provides some information... Consider:

>>> print pow.__doc__
static object pow(object x, object y)
static object pow(object x, object y, object z)

>>> print pow.__doc__
pow(x, y[, z]) -> number

With two arguments, equivalent to x**y.  With three arguments,
equivalent to (x**y) % z, but may be more efficient (e.g. for longs).

I find the CPython help extremely useful when it comes to questions on built-in modules or functions, language definition etc.

Hope this helps.

Hi Fabio,

The tutorial is meant to be ran from the Tutorial directory (there are 2 batch files to execute the IronPythonConsole from there)

Other option is to add the Tutorial directory to your sys.path:

>>> import sys

>>> sys.path.append(sys.prefix + "\\Tutorial")

>>> import first

Since the tutorial is designed to work from the tutorial directory, I'd recommend using the batch files to start the console. This way, IronPython will run in the correct directory and import lookup paths will be set correctly.

I'm new in python (and IronPython).

I have used the tutorial of IronPython 1.0 Beta, and when I "import first" I receive this error:

>>> import first
Traceback (most recent call last):
  File , line 0, in input##0
ImportError: No module named first

I think what I need set some like import "Tutorial\first" but I know not the syntax...

Someone can help?

PS: How I do to in console get help about any command?

Thanks for all!
