C___U_s_e_r_et_al folder name in postprocessing

[brockho]

Since quite some time now, I see that the automatically created folder name in the COCO postprocessing is C___U_s_e_r_et_al on my Windows machine:

A while ago, this folder name was showing the algorithms (actually algorithm name abbreviations) that were used in the comparison. That was much more helpful...

This part seems relevant.

@brockho can you share what command/code you run to get this?

[nikohansen]

The offending line is probably a few lines above

if isinstance(args, str):

which should better read

if not isinstance(args, (list, set, tuple)):

to get around any Python 2/3/unicode problems.

May be fixed with 344ad20 in the development branch, @brockho could you test this?

[brockho]

For the record, it was a simple algorithm, I postprocessed to get the error. Something like

import cocopp
cocopp.main('NEWUOA!')

With the latest fix in the development branch, the error is gone. Thanks @nikohansen!
