Why does this work?
In C++ this would go from

if (48.35 <= a <= 48.45)

to (assuming the right condition is met)

if (48.35 <= true)

because it evaluates these things right to left, doesn't it?
does python treat chained comparisons differently than C++ or is C++
behaving differently than I think it does?
Thanks for your help,
