i need to write a function that takes an input, say "'1 large banana" and then modifys it to output (1.0, 'large', 'banana')
this is what i have written so far but it seems to be incorrect
def parse_ingredient(raw_ingredient_detail: str):
raw_ingredient_detail.split()
parse = raw_ingredient_detail.split()
return(parse[float, (0), (1)])
the goal is for it to look like this
parse ingredient(raw ingredient detail: str)
outputs: tuple[float, str, str]
my friend said he used an if loop but i cant think of how that would be implemented
jolly sinew
Are you allowed regex?
quartz gulch
im not sure what that is. its just for a first semester coding project so i wouldn't imagine anything more advanced than super basic?
im not allowed import statements tho, not sure if that is relevant
jolly sinew
I see
Try returning just parse
See what you get and compare it to the expected output
You'll see that it's pretty much there after converting the first element into a float

and by this do u mean that the code is almost finished and i just need to convert the first part into a float?

Well, have you tried running the code and seeing what it outputs at this point?

i cant run it and ive asked around and im not sure why. all i have been told by other people doing this assignment is that the function just needs to be acceptable to the autograder.
for example, the assignment asks for a function like this:
get recipe name(recipe: tuple[str, str]) -> str
Returns the name of the recipe
.
the correct answer to this was
def get_recipe_name(recipe: tuple[str, str]):
return(recipe[0])

yes?
the issue is that it needs to be applicable to everything and not just "1 large banana"
im having difficulty putting it into words but the function basically needs to be able to filter anything that is put through it and output something like ['1', 'large', 'banana']
there are other ingredients such as coffee granules that need to be filtered as 'coffee granules' and not 'coffee', 'granules'
each ingredient is in the same format tho, its always amount (1, 0.25, 20 etc), measurement (large, cup, handful etc), and then ingredient (peanut butter, coffee granules, banana etc)
heres the provided example if it helps at all
Example:
parse_ingredient('0.5 tsp coffee granules')
(0.5, 'tsp', 'coffee granules')
parse_ingredient('1 large banana')
(1.0, 'large', 'banana')
someone on another forum is telling me to use the sep argument

Have a look at the maxsplit parameter https://www.w3schools.com/python/ref_string_split.asp
quartz gulch
maxsplit Optional. Specifies how many splits to do. Default value is -1, which is "all occurrences"
im going to keep reading but i gather i can use this to make the split function not split up my two word ingredients and keep them whole by telling it to only split two whitespaces instead of three
thank you for all the help so far
quartz gulch
i changed the code to this
def parse_ingredient(raw_ingredient_detail: str):
raw_ingredient_detail.split(" ", 2)
parse = raw_ingredient_detail.split(" ", 2)
return(parse)
based of the pattern i gathered in the website you sent
it failed but i think that is because i havent converted the number to a float which is the next step i am guessing
def parse_ingredient(raw_ingredient_detail: str):
raw_ingredient_detail.split(float[0], " ", 2)
parse = raw_ingredient_detail.split(float[0], " ", 2)
return(parse)
this failed. not sure how to make the number into a float
jolly sinew
Do you know to change the value of an element in a list?
jolly sinew
What you do is you index the list and give it a new value
For example
!exec ```py
example = [1, 2, 6]
print(example)
example[0] = "lol"
print(example)
@jolly sinew
quartz gulch
how do i apply this to changing the number tho? currently it is a string and needs to be a float
im having trouble picking up what you're putting down, sorry
jolly sinew
Well all you have to do is make the number into a float on the right side of the equals sign
quartz gulch
but how do i do that if i dont have an equals sign in my code?
i have the splitting part done with the maxsplit, all it needs to do now is convert the first element of the split into a float and leave the other two elements as strings
jolly sinew
!exec ```py
example = [1, 2, 6]
print(example)
example[0] = "lol"
print(example)...
Do you understand this?
quartz gulch
possibly not to the degree that you want
i think that you make 'example' gets the tuple [1, 2, 6]
then you go into 'example' and you tell the [0] element, which in this case is '1' and you tell it to = 'lol'
then you print the updated version
right?
quartz gulch
That's pretty much how you change the value of a list element
old ping but happy to say it worked
def parse_ingredient(raw_ingredient_detail: str):
raw_ingredient_detail.split(" ", 2)
parse = raw_ingredient_detail.split(" ", 2)
parse[0] = float(parse[0])
return tuple(parse)
thanks for the help!

Very nice!
