poppy Posted January 19, 2013 Share Posted January 19, 2013 Hi How can I add or subtract string? Say, stringA = ABB stringB = BB stringC = stringA - stringB = A can it be `chs("stringA")-chs("stringB")`? I'm new to this thanks Quote Link to comment Share on other sites More sharing options...
anim Posted January 19, 2013 Share Posted January 19, 2013 + is directly supported so `chs("stringA") + chs("stringB")` will give you ABBBB - is tricky, since there is many interpretations of that like ABB - BB = A, easy, but what about BBABB - BB? is it A? BBA? ABB? what you can do is `strreplace(chs("stringA"), chs("stringB"), "")` it will find stringB in stringA and replace with nothing (so the case where BBABB - BB = A) if you want something more flexible use python there is plenty of resources on python string operations and regular expressions on the net Quote Link to comment Share on other sites More sharing options...
poppy Posted January 19, 2013 Author Share Posted January 19, 2013 I see, so `strreplace(chs("stringA"), chs("stringB"), "")` means: search for "stringB" in "stringA" then replace with nothing "", right? Thanks, this help Quote Link to comment Share on other sites More sharing options...
