Python-Dictionary

[sour moth]

Hi im getting an error on python when i try making a dictionary, ive tried asking chatgpt but it doesn't understand. Perhaps someone could tell me what im doing wrong?

for context its meant to be a menu of a coffee shop, i've made a #list now im trying to set numbers to each product in the list

i havent learn much about dictionary, so im not 100% sure if its the right thing to use here to assign a number to each product on the menu

heres what ive done so far

and this is the error i am getting

You are using the set notation here

Sets look someting like this:

my_set = { 'some value', 'some other value' }

While dicts look something like this:

my_dict = { 'some_key': 42, 'some other key': 'some value' }

So you should have the price for each item right after the item, not in a list after all items

[sour moth]

oooh alright

thanks

[sour moth]

can i ask what sets are for

when would you use those

[minor elm]

Python sets are more or less the math sets

Dictionary goes with value and key

It better to make it an array which is indexed and because we type using 1 you decrease the user input by one

[minor elm]

How's that related? 💀

[bold rain]

I'm saying he should use an array instead of dictionary

[minor elm]

For the prices? Hell nah

For the menu options: Maybe but meh

[bold rain]

Not prices the menu

Looking at code he was using dictionary to index the input from the user
But it's wrong

[minor elm]

I have no idea what you're talking about, are we looking at the same code? 💀

[bold rain]

Check his data dictionary

[minor elm]

he made some modifications though?

[sour moth]

btw those are not the prices

im setting numbers to each item in the menu

[minor elm]

Fair enough

[sour moth]

its like those screens you see in mcdonalds

to order food

[bold rain]

Thank you

That's what I wanted him to know

[sour moth]

whats the command

[bold rain]

Just use the array you created first

[sour moth]

not yet😭

[bold rain]

It's indexed starts from zero so of user inputs 1 subtract one from any user input

[sour moth]

oh wait

i think im catching on on waht you're thinking

[bold rain]

Take out the data dictionary and maintain only menu

[sour moth]

where it says if user input 0: print "return main menu"

thats a different section

im trying to assign a different number to each item in the menu

[sour moth]

so lets say a customer wants a cappuccino

theyd have to pick 2

if they want an americano theyd have to pick 6

[bold rain]

No need for that
Use the index
If user inputs 2 the index is 1 so subtract one from user input

You know programming starts counting from 0

Copy and paste your code let me help you on it

[sour moth]

i cant rn i have python on my laptop

im on a diff device rn

[sour moth]

Yeah

[bold rain]

I have a better version of your code idea in my head
I really wants to help you debug
You can even use a for loop to number them so that there is no need to tell the user to input a number but rather pick a choice

[sour moth]

yeah my tutor accidentally showed the class his code and its what he used. but i dont wanna use it since we havent been taught that yet

probably gonna get taught that next week

[bold rain]

Ooh cool
But Don't wait for the class explore

[sour moth]

you right

but

its late where i am and class starts early tomorrow

so i have no choice😂

ill be back after class tomorrow if thats fine with you

[bold rain]

Alright 👍
Best luck
I'm a student also
