[Help-glpk] Please help me debug this small python-glpk program

[Christophe-Marie Duquesne]

Hello help-glpk,

I can't find a mailing list for the python-glpk binding[1], so I
figured I could ask my question here since this library makes the code
look very much like C.

I want to formulate a small LP problem (3 variables, 3 constraints)
and to write it on disk. Attached as "expected.lp" is what I want, as
"obtained.lp" is what my code produces, and as "glpk_mip.py" is the
code itself. At line 18, I use glp_set_col_kind(prob, 3, GLP_IV) to
make the variable z an integer variable. However, this variable is
reported as "general" in obtained.lp. Should you read this code as C,
would I be missing something?
