How to install a Python Recipe File (.py)? -

I'm new to Python I'm currently on Py3k (Win).

I'm having trouble installing a .py file. In fact, I want to use the recipes given at the bottom of the page. So I want to put them in a .i and Import in any of my source code.

So I copied all the recipes to a recipes.py file and copied them to C: \ Python3k \ lib \ site-packages .

Now, code> Import works fine, but when I try to call any function (eg. take ), Code> global name is not defined 'islice' ... so I thought, I should import itertools at recipes.py

Do I still get this error? Do I need to change all the examples on the itertools. & Lt; Funcname & gt; ? How can I make a global import? Is this a new Py3k change? Am i missing something

Thanks in advance, :)

Two closely related issues

First of all, within Recipes, you need access to all itertools.

At the very least, this means that you

  import itertools  

at the top. But in this case you will need to qualify all these Iteratol functions as the itertools. & Lt; Funcname & gt; , as you say (you can import it as , import it as and then it. & Lt; phonka name & gt; . )

Second, you can

<<< Code>

But you will have to put all necessary functions in the list.

Finally, at least

This is dangerous because it pollutes your namespace with everything > to itertools , which is considered bad and unruly, but in this case is probably not terrible.

Second , you have the same problem with all of your code that uses recipes.py ; If you have to qualify or import everything explicitly, recipes from import

  recipes of recipes. Take (...)  

Or

  take the import (...)
