like expand.grd. Python has many modules, like itertools that do things
including combinations but perhaps not designed for your case.
Here is a version of your scenario:

c = range(5)
list(itertools.product(a,b,c))

Using the following code looks like a much better solution than my current
Python code indeed.

The next question is how I can generate ndarray of h,k,l indices. This can be
easily done from a Python list by using

Is there a reason you cannot solve this mostly outside numpy?
It looks like you could use numpy to select the numbers you want to compare,
then call one of many methods you can easily search for to see how to use

For this to work, the Python implementation should use the same

It works in python3, so I guess my problem is that I'm

I don't see any relevant options in the configure help.

At least this attempts to abstract the problem of iterating over a file

modify the last attempt to open the file twice, which would
work, but seems like a kludge (subject to race condition, inefficient).

Just FYI, I use Erc (in Emacs). I'm not a very advanced user, perhaps,

then there's already at least one.

Traceback (most recent call last):
File "C:\TEST*.PY", line 8, in
SetClipboardData(CF_UNICODETEXT, "0")
pywintypes.error: (0, 'SetClipboardData', 'No error message is available')
Can anyone shed light on this?
Best wishes

I simply am thinking that people who do not allow me to easily reply to them
