Hi there,

Try using this block.

This tests if piece is in text.

Edit: If you want a word in a list, try these:

hi there, thank you for helping me
I already try your block but it always return true on last list (sphagetti)
when i try to change label 1 to pizza it return false
i try to change other, the return is false.
why is this happened?

[TIMAI2]

Perhaps try this way

[gordonlu310]

Sorry, it's my fault. I realized what's the problem now.

Do these work?

[gordonlu310]

This might work, but if the labe's text is hello world and there is only hello in the list, it returns false.

[gordonlu310]

@Redynan_frozt If the label's text is France and the list's version is france, do you want it to return true?

[TIMAI2]

In which case

[Redynan_frozt]

hi @TIMAI2 thank you for your help
i already try your block but it doesn't work. coz the text in label 1 is "i want pizza". and i need to recognized if in the list there is food that in label 1

[Redynan_frozt]

thankyou so much @gordonlu310 I already try yur block and it works like charm
thankyou so much your guidance

[Redynan_frozt]

but how i can check from label 1 "i want pizza" if in the list and extract the word "pizza" from label 1?

I already try this block but the result in label 2 is [false, false, false, true]

[gordonlu310]

Because you did not use the is in list? block? Check the screenshot again in post #4.

This could other way to examine the presence of word(s) from a list in a sentence

With one correction, since earlier code block wasn't producing result with confidence.

Here is a tutorial (https://imagnity.com/tutorials/app-inventor/list-blocks-on-app-inventor/) by Sajal. Look for 6. Search for an Item. The tutorial explains why the method 'works' and you may find the explanation useful.
