Question #266772 on Sikuli changed: https://answers.launchpad.net/sikuli/+question/266772
RaiMan proposed the following answer: I remember you said that: false or false is false true or false is true false or true is true true or true is true this is for an or like your while not exists(image1, 0) or not exists(image2, 0): wait(1) shorter: while condition1 or condition2: wait(1) where condition1 is not exists(image1, 0) condition2 is not exists(image2, 0) the while loops as long as condition1 or condition2 evaluates to True the last 3 cases in the little logic table. hence the while only stops running if condition1 or condition2 evaluate to False which is only the case if BOTH condition1 AND condition2 evaluate to False, which is only the case, if BOTH images are there. --- But wouldn't that be the case for the if statement? yes, the if statement has the same logic, but condition1 and condition2 are the opposite compared to the while, since we want to check wether we have to END the loop. the while condition tells, wether the loop should continue to run. -- You received this question notification because you are a member of Sikuli Drivers, which is an answer contact for Sikuli. _______________________________________________ Mailing list: https://launchpad.net/~sikuli-driver Post to : sikuli-driver@lists.launchpad.net Unsubscribe : https://launchpad.net/~sikuli-driver More help : https://help.launchpad.net/ListHelp
