Python help channel opened

Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Closes after a period of inactivity, or when you send !close.

this is the current output to give an idea of the goal. it should be the height of each instead of "10-12in" for both

A problem with sharing screenshots is it is difficult to ctrl+f "compareTwoItems" in a screenshot.

mortal forge
#

you should really consider a dicti nstead of the two lists

#

a dict of dicts even

frigid lion
#

two lists is a requirement

mortal forge
#

ok

frigid lion
mortal forge
#

you need to get the indices of the breeds then, and use them in that function

Pasting large amounts of code

If your code is too long to fit in a codeblock in Discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the Paste! button in the bottom left, or by pressing CTRL + S. After doing that, you will be navigated to the new paste's page. Copy the URL and post it here so others can see it.

Formatting code on Discord

Here's how to format Python code on Discord:

```py
print('Hello world!')
```

These are backticks, not quotes. Check this out if you can't find the backtick key.

For long code samples, you can use our pastebin.

cats = ["meow", "purr", "nap"]
cat_stats = [[5, 1], [3, 2], [4, 0]]

print(cat_stats[cats.index("purr")])

@mortal forge :white_check_mark: Your 3.12 eval job has completed with return code 0.

[3, 2]

#

that should work

mortal forge
#

do you see how you can use catData[cats.index("Main Coon")] to access that particular cat?

#

given that you got Main Coon from the user

frigid lion
#

in the print statement?

#

I'm not sure what your findIndex function is supposed to do

#

the iteration is pointless. if both cats are there it will return 0, otherwise it will return -1 after making the same check needlessly many times

# 
  if index != -1:
      if comp1 in cats and comp2 in cats:
        # ...
  else:
      print("One or both of the cat breeds were not found.")

also, here you are doing the job of findIndex again

try this:

def compareTwoItems(comp1, comp2, cats, catData):
  a = "Adult Height"
  w = "Adult Weight"
  p = "Average Price"
  
  if comp1 in cats and comp2 in cats:
    cat1 = catData[cats.index(comp1)]
    cat2 = catData[cats.index(comp2)]
    print(cat1, cat2)
    print(f"{a:15}{w:15}{p:15}")
    data = input("What data would you like to compare?: ")
    if data == a:
       print(f"{catData[index][0]:20}{catData[index][0]:20}")
    elif data == w:
      print(f"{catData[index][1]:20}{catData[index][1]:20}")
    elif data == p:
      print(f"{catData[index][2]:20}{catData[index][2]:20}")
    else:
      print("Comparison not found (check casing)")
  else:
      print("Invalid cat breeds provided.")
#

cats.index(comp1) finds the index of comp1 in cats, then by calling catData[] on that index you find the stats of that cat

#

if you want to keep working with your own structure, you could make findIndex do the job of finding the indices of both cats

frigid lion
#

That does make sense

#

I get an error because 'index' is not defined

#

would that mean I'd have to make findIndex do that anyways?

mortal forge
#

!e

foo = ["a", "b", "c"]
print(foo.index("b"))

I haven't used it much tbf, but I would expect your python should support it

#

it's ok if you want to look for it yourself though
