You're working for a restaurant and they're asking you to generate the sorbet menu.

Provide a script printing every possible sorbet duos from a given list of flavors.

Don't print recipes with twice the same flavor (no "Chocolate Chocolate"), and don't print twice the same recipe (if you print "Vanilla Chocolate", don't print "Chocolate Vanilla", or vice-versa).

The flavors are:

I have a simple ice cream program, everything works. But how do I loop a single input like scoops if the input is invalid? Currently if the input is incorrect it re-asks the user for the first input again. Meaning if I enter vanilla for the flavor and 7 for the number of scoops, it will print the error message, then instead of re-asking how many scoops you'd like, it asks you what flavor you'd like. How would I fix this for my three inputs throughout the program? I would still like the program to restart after a valid order is entered. Thank you for your time.

Program code:

I am learning Python, one month in and I am struggling with the following problem:

An ice cream shop has a list of flavors:

FLAVORS = [ "Banana", "Chocolate", "Lemon", "Pistachio", "Raspberry", "Strawberry", "Vanilla", ]

They want to build a list of all the alternatives of a 2 balls flavoured ice creams. The flavours cannot be repeated: ie. Chocolate Banana cannot be listed as Banana Chocolate is already in the list. I have to print the list.

Here's my code:

I have this program that has two exceptions one for number of scoops and one for flavors. When I try to run the program I get a type error: main() missing 2 required positional arguments: ‘flavors’ and ‘scoops’

How do I fix this?

Code:

In this program I have created a class for ice cream flavors and a FlavorsError class. There is also a Scoops class and a scoops error class.

Problem 1 - if your input is greater than 3 for number of scoops it should print the scoops error message.

Problem 2- if your input is not listed under flavors it should print the flavors error message.

For both, the error messages do not appear if data does not match the class information.

Code:

I have plotted a donut chart with the code below:

My company is currently trying to build a multitenant chatbot using Google Dialogflow. We're exploring the tools at our disposal, but the documentation on the topic is still a bit scarce. Our understanding and definition of multitenancy, in this context, would allow us to have slightly different conversational flows depending on the company the end user works for. For example:

User A from company Foo wants to order an ice cream. Company Foo provides a set of flavors (chocolate, vanilla, mint) and only serves ice cream cones, but lets users add garnishes to their ice cream (chocolate chips, sugar sprinkles).

User B from company Bar wants to order an ice cream. Company Bar provides a set of flavors (strawberry, pistachio, lemon) and serves ice cream cones and cups, but offers no garnishes.

Both users should have the same exact conversation, except that the available lists of flavors and ice-cream containers would depend on the tenant. Furthermore, there should also be the option to extend parts of this conversational flow, such as company A providing the ability to add garnishes. Both conversations should start and end with the same intent (I want an ice-cream/I am ready to pay).

Our secondary goal here would be to minimize the Dialogflow-side redundancy: ideally, there would be only one agent, and ideally, intents that require no duplication should not be duplicated.

Our architecture is not client-driven; the client is always intercepted by our back-end server (C#), which is responsible for handling the interop with Dialogflow. We think this gives us more flexibility and better integration with our existing stack.

We have identified these promising features:

• Sub intents
• Input contexts
• Overrideable entities
• Mega/Sub agents

But we haven't identified a clear path yet. We're also considering the available alternatives, such as Microsoft's BotBuilder, Amazon's AWS Chatbot and the open-source ChatterBot.

In short, is there a best practice when it comes to this? If not, any ideas and thoughts on the matter would be very welcome.

In CLTL2 there is a struct example ice-cream-factory as follows, which would allegedly create two constructors. Here is the structure definition:

I would like to keep object keys when reducing a CSV data set using JavaScript's map function (if this is in fact the right approach?)

I have read a top SO thread on preserving keys, but the solutions given require external JS libraries (underscore or lodash). I'd prefer avoiding anything but 'vanila' JS if possible.

For example:
