Alienbot instruction on if-elif-else condition

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

I thought this worked fine when I went through it yesterday, but after coming back to it today I am also having the same issue. I’m not sure why this is happening, but will come back to see if anyone else can solve this.

I’m not exactly sure why it doesn’t work with the else statement at the end, but I found this old post:

If you remove the else statement altogether, the code won’t skip the other intents.

Hope this helps!

Hi kenandutan,
thanks for sharing that. example The problem shown there is familiar to me. And I think that problem has the same root cause, that I’m adressing in my original post.
It looks to me, like the source lies within the definiton of the ‘.match_reply()’ method.
To be more specific, In the indentations of the if_elif_else conditions under the for loop.

The logic is the following.
"As the if_elif_else_conditions do encompass all possible outcomes for the (local) variable ‘found_match’,
the for loop will only work through the first iteration. It will never get passed the first loop.
Because for any possible shape/content/form of the variable ‘found_match’, there is an case (‘if’-case, ‘elif’-case or ‘else’-case), that implements the return and therefore ends the function before the second iteration of the for loop.
Does this make sense to you?
Don’t know if I made myself clear? (I’m just starting to discuss code on forums).

Cheers Nouma
