There are tons of reptiles that lay TSD (temperature sex dependant) eggs. Some lizards and turtles. Some the higher temps cause more males, some the higher temps cause more females. Most TSD reptiles are shallow nesters too.
However, I have not heard of a single snake with TSD.
People have experiemented with incubating other reptiles for tempeature sex dependancy too. Bearded dragons are not TSD; however, if incubated at high temperatures, all eggs will generally hatch genetic males which appear to be female. "Hot" females is a term commonly used when this occurs. They are almost always aggressive and nonreproductive.
No one experiements with ball pythons. People are too worried about how to mix and match mutations to focus on actual research....not to mention varying from the norm with incubation can be risky and really hurt the wallet of someone expecting to sell the offspring.
