Join Jeremy Graham for an in-depth discussion in this video Logical operators, part of Dynamo for Revit: Python Scripting.
- [Instructor] While comparison operators…are good at comparing values,…logical operators allow us to compare booleans.…This becomes very useful…when comparing two or more different value comparisons.…So for example, say we had a sphere in Dynamo,…and we wanted to check if the sphere's radius…was above a certain number,…but also positioned above a particular z-value,…we could check these two conditions at once…to see if both were true,…or both were false using logical operators.…Let's start with having a look at what the AND operator is.…AND operators are useful if you want to check…if two boolean operations or booleans…are equal to true.…
Say for example we had two operations.…Two is greater than one, and one is less than five.…As we have learned,…both of these operations will equal true.…If we compare these two operations,…we're essentially comparing true and true…as both equal true and therefore the result will be true.…As when comparing two booleans with the AND operator,…two trues will always result in a true.…
