🔒 getting a certain uplet in a dictionary | Python | Page 1

void saffron May 21, 2024, 5:04 PM

#

I have a dictionary in which are lists composed of tuples and i want to check if the tuples i ask for is in the dictionary. heres an example of what i m trying to do:
i have a coordinate (1,1) ->one of the keys of my dictionnary from here you can move to [(1,2),(2,1),(5,1)] -> values of the key (1,1). so i want to ask the person through the console where they want to move. To do that i want to check if its in the values of the key (1,1) and then i want to repeat the whole process until i reach a certain coordinate that i told them to reach.

"Uplet": I'm assuming you mean "tuple"?

void saffron May 21, 2024, 5:05 PM

#

tuples xd idk why i always say that

#

it has become a common joke with my friend now

barren ferry May 21, 2024, 5:06 PM

#

Can you show an example dictionary structure?

void saffron May 21, 2024, 5:07 PM

#

i want to basicly check if the move they want to do is a possible move

#

i know i should get the list of tuples from the previous coordinate and see if the one they want to move to is in this list

#

i just don t know how to do it

barren ferry May 21, 2024, 5:10 PM

#

Which list in that dictionary are you wanting to check for a example input?

void saffron May 21, 2024, 5:10 PM

#

if my start is (0,0) and the input is (1,1) i want to check if (1,1) is in the key (0,0)

barren ferry May 21, 2024, 5:13 PM

#

Oh, this sounds pretty simple. You should just need to get the value of the 0,0 key, and then check that list.

void saffron May 21, 2024, 5:14 PM

#

if

#

if value in key[(0,0)] like this?

barren ferry May 21, 2024, 5:14 PM

#

Assuming the dictionary is called key, then yes, that looks correct.

void saffron May 21, 2024, 5:15 PM

ok nice

how do i ask for

a tuple through my console

int won't work there because a tuple isn't an int.

void saffron May 21, 2024, 5:16 PM

but tuples aren t int

#

what are they?

barren ferry May 21, 2024, 5:16 PM

Tuples

void saffron May 21, 2024, 5:16 PM

#

tuple(input()) ?

#

this seams wrong 🤣

barren ferry May 21, 2024, 5:17 PM

#

No, accepting a tuple will be slightly harder than a single int. What exactly are you wanting the user to type?

void saffron May 21, 2024, 5:17 PM

#

the next coordinate like (1,1)

barren ferry May 21, 2024, 5:18 PM

#

If you want them to include the () and comma, ast.literal_eval would be the cleanest way.

void saffron May 21, 2024, 5:18 PM

#

and what other alternative are there?

barren ferry May 21, 2024, 5:19 PM

#

Accepting it as a string and parsing the string yourself. Or changing the format you expect the user to enter the data (like 1 1 instead of (1, 1)).

void saffron May 21, 2024, 5:19 PM

#

hmmm

so technically i could accept it as a string but if they make a typo its going to count it as wrong?

You would need to do the input validation yourself and re-ask for input or something in that case.

Making sure (validating) that data is what you expect it to be.

Ensuring the user gave you the correct data in the correct format.

do i need to do : if chemin in dic_Voisin[[debut]]: this?

barren ferry May 21, 2024, 6:02 PM

#

I mentioned input validation because that's a pretty standard part of taking input from the user. Eventually, you'll be expected to handle that.

The real thing you need to handle is turning chemin into a tuple. I mentioned ast.literal_eval, and just parsing the string yourself if you don't want literal_eval.

void saffron May 21, 2024, 6:02 PM

if i do this i end up with unhashable type: 'list'

barren ferry May 21, 2024, 6:04 PM

Or, just do your own parsing with functions like str.split.

#

Split the string on the comma, then remove the () to get the numbers, and make the tuple yourself.
