that's pretty good, just a little Syntax mistake you need to finish the line with :
except ValueError:
return("And here something that explain the Error: Like \"num1\" or \"num2\" coulnd't cast to float")
Greetings Julian

9,802 PointsDear Bo,
actually for this "task" you don't need a else Block. In words you try to cast and add the two numbers and might an error will happen you return a information or do something eles inside of
except ValueError:
Like i wanna do something a+b but if an error happen "catch" this error and do something else mostly by this course just return a errormessage.
Greetings Julian

Courses Plus Student 848 PointsWell actually, I'm supposed to add an else statement after the except block but I can't figure out what I'm supposed to put in the else block.
