ostrich | An optimization toolkit for model calibration | Camera library

I'm essentially making a counter and it counts the number of times a name appears in a list. I'm trying to use a function so I can easily do it for all the names. It works fine when I don't make the code a function but as soon as I do it no longer returns the value of y.

This is an incomplete tree diagram I made to classify this list of animals:

horse, cow, sheep, pig, dog, cat, lion, tiger, whale, dolphin, seal, penguin, ostrich, sparrow, spider, ant, bee, wasp, termite, octopus, squid

I havent finished putting in dog, tiger, lion, etc. just because the application required me to buy some subscription for more shapes and i wasn't gonna do that, but that doesn't matter cos I can visualise the rest. My question is; In python code, how can I make a program that asks the user yes/no questions continuously until it can make out what animal it is out of the list. I can obviously do this with lots of IF statements, or with OOP and using attributes, however both solutions require me to ask EVERY single question, which would amount to quite a lot of lines of code, and it would be quite ugly. How do I make it, for example, so that if the user says that their animal is aquatic, it no longer asks any of the questions that don't apply to the animal. For example:

If I pick wasp, and I answer yes to the question "Is your animal a land animal?", then no to "Is your animal a mammal?", then yes to it being a carnivore and being able to fly, how do i make it so the program will only branch to those questions? Basically, how do i code a tree diagram that follows the user's inputs? (I dont need any GUI)

Consider the following two data frames:

As a follow-up question to Efficient ways of creating matrix based on vector matches, how would I go about if I would like to produce a boolean matrix with matches between each column in Y and X:

SCENARIO

I have a program in Java that randomly puts out text as follows:

1 egg1 chicken and 2 ducks

2 cows1 pig1 egg and 2 cats

1 hour1 dog1 ostrich 2 cows and 3 chickens

QUESTION:

How do I add a comma and a space within a string immediately before the occurrence of all numbers between the first and last ones? That is, how can I format these strings so that these cases look as follows:

1 egg, 1 chicken and 2 ducks

2 cows, 1 pig, 1 egg and 2 cats

1 tractor, 1 dog, 1 ostrich, 2 cows and 3 chickens

As you will see, in each case I:

WHAT I HAVE SO FAR:

I already have it successfully handles cases of:

1 object:

1 cat

2 objects:

2 cats

Variants of Multiple Objects:

3 cats and 1 ostrich

and

1 truck and 6 gnomes

What I need to do is:

1. Identify is a string has 3 or more numbers.
2. If so, skip the first number in the string.
3. Find the next occurring number that is not the last one.
4. Add " ," to it.

I can successfully go through the string and count the numbers it has in it:

I'm trying to extract the text from this html structure:

I wonder why my first code doesn't work and the second does. I thought they're basically the same.... Looks like var inside if statement doesn't seem to be processed as expected. Could anyone please clarify why it doesn't work?

I have a Cucumber-Selenium based test written using Spring Boot. The problem is that if I have just one step definition file GoolgeCalcStepDefinition.java then the program works and test passes without any issue but as soon as I added BingSearchStepDefinition.java along with feature file then I get following error.

I googled around on how to configure Spring Boot with Cucumber but most of the examples/articles available online shows only one step definition file.

I have some items in a nested dictionary and I need to match if any word in a sentence matches the values in the dictionary. If it does, it returns all the keys from the nested list.
