are small (<200kb) so I don't believe it's an upload issue (internet access
is fine). Eventually the connection times out.

Hi Guys,
I just joined the group and I hope that I can help and be active.
I have a question about python. I wrote a code on python 2.7 and I want to
choose from the list of names that I provide n!. I execute the code but the
result or output is the numbers. I want the people names are the resu

Hi folks.
I've been benchmarking some python modules that are mostly variations
on the same theme.
For simplicity, let's say I've been running the suite of performance

Below is my test code that implements both of these things
