prspace - Probability Spaces with the Same Syntax in R and Python

Write probability statements such as 'Pr[X == 0] <- 0.25' and read them back with 'Pr[X == 0]'. Events can declare their support (real, integer, count, or a finite set), and anything the rules of probability then pin down, such as complements and totals, is derived. Assignments that contradict earlier ones are flagged with the range of values that would have been consistent. A companion Python package on PyPI offers the same syntax.
