I'm puzzled over the pycalln opcode,

it seems not to work as expected.

Could perhaps someone else test the csd (below) and report?

I get this on Csound6. Seems to work:

SECTION 1:

new alloc for instr 1:

 i1     0.00000

 i1     0.00000

 i1     3.00000

B  0.000 ..  1.000 T  1.000 TT  1.000 M:  0.00000  0.00000

Score finished in csoundPerformKsmps().

inactive allocs returned to freespace

end of score.              overall amps:  0.00000  0.00000

           overall samples out of range:        0        0

0 errors in performance

Thanks for testing, but it does not seem to work on your setup either,
it should have returned

 i1     1.00000

 i1     0.00000

 i1     3.00000

or preferably

 i1     1.00000

 i1     2.00000

 i1     3.00000

(if it would accept both arguments)

I get the same as you

 i1     0.00000

 i1     0.00000

 i1     3.00000

which indicates that the arguments are not passed from csound to the python function
