Did I get it right?
The Alienbot project in tasks 28 till 30 expects the if-elif-else conditions to be put under the for loop.
But in that case the for loop will iterate only once:
a) if it matches the first intent, the corresponding output will be delivered and everything is ok.
b) Otherwise , if the first intent isn’t matched, the else condition applies and this will break the loop.
Personally I conlcuded to change the code by reducing the intendation of the if-elif-else conditions.
Given the above mentioned problem the instruction makes no sense to me. Sorry.
Now I have a solution but am wondering.
Does python allow for a solution that strictly follows the instruction on tasks 28 till 30, to put the else-condition under the for loop without getting the above mentioned problem?
I#ll be happy about replies
