do you know how lists work?
acoustic orchid
yeah
leaden grotto
!e
l = ['cat', 'dog']
print(l[0])
:white_check_mark: Your 3.12 eval job has completed with return code 0.
cat
yeah i get it
leaden grotto
dicts are the same; they just don't use integers as the indexer.
acoustic orchid
yeah i understand dictionaries i just dont get it how this code works and how it uses then
them*
leaden grotto
!e
d = {"animal": "cat", "sound": "meow"}
print(d["sound"])
:white_check_mark: Your 3.12 eval job has completed with return code 0.
meow
hollow patrol
dicts also have a special method called .get()
leaden grotto
ah get is kinda like [] but it gives you the chance to substitute something if it's not found.
acoustic orchid
can you tell me exacly whats going on here? mostly in the second last line
raven joltBOT
!e
```py
d = {"animal": "cat", "sound": "meow"}
print(d["weight"])
```
:x: Your 3.12 eval job has completed with return code 1.
001 | Traceback (most recent call last):
002 | File "/home/main.py", line 2, in <module>
003 | print(d["weight"])
004 | ~^^^^^^^^^^
005 | KeyError: 'weight'
so that's what happens if it's not found.

the name is quite apt here, you can think of the emoticon (like :) or :D as the word, and the actual emoji 😊 and 😀 as the definition. python is essentially searching a dictionary to find the definition of a word
leaden grotto
!e
d = {"animal": "cat", "sound": "meow"}
print(d.get("weight", "I dunno how much it weighs!!"))
:white_check_mark: Your 3.12 eval job has completed with return code 0.
I dunno how much it weighs!!
what means the (word, word)?
leaden grotto
and that's how get works
so get(word, word) means "look up word; if it's not there, just return word itself"
acoustic orchid
and what does the += mean in this case? it adds the text to the empty string?
raven joltBOT
!e
```py
s = "wat"
print(s)
s += "; I said WAT"
print(s)
```
:white_check_mark: Your 3.12 eval job has completed with return code 0.
001 | wat
002 | wat; I said WAT
i dont understand it
leaden grotto
try it and see
acoustic orchid
what does the word represent?
leaden grotto
some text from somewhere
acoustic orchid
from what ive typed?
leaden grotto
one of the words in the message
it says words = Messsage.split(' '), right?
That's what "words" is
leaden grotto
!e
Message = "It's like a jungle sometimes"
print(Message)
print(Message.split(' '))
:white_check_mark: Your 3.12 eval job has completed with return code 0.
001 | It's like a jungle sometimes
002 | ["It's", 'like', 'a', 'jungle', 'sometimes']
it goes thru the dictionary and compares the word with all the strings in the dictionary
and if it finds a match it converts it, and if it doesnt it returns the word?
leaden grotto
yep
acoustic orchid
hmm
leaden grotto
we call it a "dict", not a "dictionary"
acoustic orchid
alright
okay so
the second word in get(word, word) makes it so if no match found, the word returns?
sudden arch
we call it a "dict", not a "dictionary"
Some of us are happy to call it a dictionary, because that's what it is. The type of a dictionary is dict.
leaden grotto
hmph
because OP said "dictionary" I started scanning the code for a reference to /usr/share/dict/words, and was about to tell them they're mistaken, the code isn't looking in the dictionary, &c &c
I don't care what it "is"; I care what other people think of when I use the word.

Yes.
acoustic orchid
and the first word?
leaden grotto
that's the word from the message that we're trying to convert into an emoji.
You should really play with the code; it'll be easier than asking us.
acoustic orchid
i guess?
sudden arch

The dict.get method is specified here, FYI: https://docs.python.org/3/library/stdtypes.html#dict.get
The description is short and to the point.
