Could you please tell me what's wrong? It would be really helpful if you provided the error that you are getting. The syntax of your code looks fine so it is likely an indentation issue and we would need to see it properly formatted in order to troubleshoot. But here is a properly indented version based on the code you provided and it seems to work fine for me.

Again, I'm not exactly sure what error you are getting or if you aren't getting an error at all but the code isn't doing what you want it to. Thanks, but the problem is that i do not see the list after i type 'DONE', that is supposed to happen. Note that these are not quotes.

After the first set of backticks, you can add the name of the programming language for extra syntax formatting. Just copy and paste your code exactly as you have it in the challenge and it'll automatically set the spacing for you. Are you sure you are entering the word DONE correctly?

It should be in all capitals, with no quotes. Are you entering all the words in one input? Because then it won't work like you are expecting. Each item needs to be entered in separately. Otherwise everything you enter on one line will be treated as one item. Posting to the forum is only allowed for members with active accounts.

Hi Augustine, It would be really helpful if you provided the error that you are getting. Would you be able to re-format your code on your original post so we can troubleshoot it? How do i do that? That is very strange. Your code works perfectly for me. And are you making sure to enter each word separately?By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Below is a basic shopping program which will return a list of items to buy based on the selected food. I'd like to improve it and allow user to select several foods at once e.

You have multiple items you want to present at the user, and you are hard-coding those values. This makes a lot of effort for you as you have to repeat yourself a lot. Look at your choice lines, they all come to basically the same thing. You also repeat yourself by defining what the numbers link to in your description, and in your code. Let's try to simplify this with a data structure. Here, we make a list of all the options - a list of tuples, defining the name and set of items for the given food.

We use a set here as we don't need to order the items. We can then make our question, rather than manually constructing it, we can construct it from our list of options using a loop:. Note the use of the enumerate builtin in order to give us the numbers for the options.

As you want to start from 1, and Python counts from 0 normally, we pass that in too. This gives us our output, but we can now easily add more items without modifying the existing code.

We first have to change the string to a number, and then take away one as Python counts from 0. This gives us:. The only issue now is what will happen if the user types in a number out of range or an word instead, for example. You could check it before you convert to an int and use it, but it's Pythonic to simply try it, and catch the thrown exceptions upon failure. For example:. This makes the entire program much smaller, and also note how easy it is to add new items, you simply add them to the list.

So how do we deal with multiple items? Well, that's pretty simple now too. We can take the user's input, split in on commas, and strip the values to remove any spaces, then do the same thing we did before:. This works, printing out multiple buy lines, but it's not optimal, a better idea would be to produce one bigger shopping list containing all of the needed items.

We can build this by building up a set of all of the items as we loop, then printing out that set. This is a little inefficient and ugly, however. Python has some built in functionality to build up lists - list comprehensions. We can do this operation like so:. Now we need to print out all the values in the list. Remember that this is a list of sets, so ", ".

We have two options here. We can either use a generator expression to join the sets first, then join the joined strings:. Or, we could use itertools. This is short, easy to expand on, and functions well. There are some other issues you could deal with how do you want to handle multiple of the same item?By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Code Review Stack Exchange is a question and answer site for peer programmer code reviews. It only takes a minute to sign up. This is a shopping list program made in Python 3 and it will send the list by email.

I am not very experienced but I consider this program as a starting point to what I will do next. Functions, functions, functions. They make your life a lot easier, because they allow you to give a clear name to things and even add a docstring to it to add even more description of what the function does.

It also means that instead of having to read a whole block of code it is usually enough to read the name of the function to know what is happening if it is a good name, of course, one of the harder problems in computer science. Now, let's get to defining some functions. Ideally each function is responsible for one thing, and one thing only the Single Responsibility Principle.

Note that in your case calling str on input is not necessary in Python 3, since it always returns a str. But here we need it to allow accepting arbitrary types. This even allows you to aggregate items if I enter an item multiple times:.

This would normally lead to a KeyError whenever name is not already in the dictionary, but will work out fine if items is a collections. This function could probably be split up further to allow e. Note that catching all exceptions with a bare except means also e. Instead at least catch only Exception and be more specific if you can. You should also print to the user which exception occurred, for which you can use the as keyword.

So you could also make this into a class:. Welcome to Code Review. Since each product is associated with its own quantity, say hello to a namedtuple :. You wont need the string manipulation, or the loop.

Just printing out the products list should give you something like. Each element of the list now has name and quantity as its property as well. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

Aug 5, Jul 29, Aug 15, Jul 28, Jul 27, At one point in the program, the user is asked how many items are on their shopping list.

What I want to do is take the number that the user inputs lets say it's 5and the program then requests input from the user for 5 different grocery items item name and cost. For the time being I've just added a bunch of code to accept values for 1 - 10 items, but I'd like to have a small chunk of code that can accept any value and request the appropriate amount of data.

I'm terrible at explaining this, but basically if the user inputs 5 for their number of items, they're required to input information for 5 items. If they put 30 for their number of items, they're required to input information for 30 items. So when printed on their screen it would look something like:.

It would be easier to help you in your problem if you posted your code and error message you are getting. What I'm asking is HOW I could code the program to handle any value without having a section of code for each value.

That's obviously not exactly what my code looks like, but it's to give you an idea. Look into dictionary. Example Banana is the key and price is the value. So if you call key you get price. Here is a code example you can look. This code will run in a loop given bye argument number given to function. And save result to a dictionary,that you can use later. Ok so now that the user entered the information and it's stored in a dictionary, how can I 'access' each piece of information individually.

Also the version in your quote is OK in 2. Copy paste error? Return value of that function is None as there is no return statements.

I'm currently learning Python, and at the moment I'm writing a simple grocery list program. So when printed on their screen it would look something like: How many items on your list?
