Hi,
After computation of few array, when I am using plot(x,y) command I get

What does the notation "_" stands for ? Is it a sort of /dev/null ?
I know that in the terminal it represents the last printed text.

PyPDF (and others) provide a very nice mechanism for creating and
manipulating PDF documents. Is there any *Python* module or technique
to turn a PDF document into Postscript [to print, for example]?

My favorite approximation is: 355/113 (visualize 113355 split into two 113 355
and then do the division). The first 6 decimal places are the same.

I have found this approach problematic if you have packages separately
developed and maintained in different directory trees, resulting in
more than one PYTHONPATH entry with the same root metapackage name.
What happens is that only the first entry in the PYTHONPATH containing
the metapackage name

Since pi is irrational
There are a few long strings, but have fun yourself with the pi digit searcher:

Longest string I heard of was nine 6's in a row, so search for 6 and
see what you get.
