Yep.
His advice seems to be sound. A smaller cage may do the trick.

Air temp should be 80F, basking area should be 90F, there should be 2 small, tight hides (not half-logs), and a water bowl. Humidity should be 60%.

Rubbermaid or Sterilite bins are frequently used to house ball pythons. It's much easier to keep humidity up in a bin than a glass tank, and they also seem to hold heat better. Just be sure that the lid is clamped tightly (buy clamps). You can use a soldering iron to poke a row of holes along the top edge of the bin for ventilation--it's not necessary to overdo it, a single row will do. You can always add more if there's too much condensation.

It should be about time for males that were off feed for the winter to begin feeding again.
