🔒 noob question but i really struggle with this lmao

[lethal condor]

setm = set()
for _ in range(m):
    setm.add(map(int, input().split()))

n = int(input()) 
setn = set()
for _ in range(n):
    setn.add(map(int, input().split()))

symdiff = setn.symmetric_difference(setm)
sortdiff = sorted(symdiff)

for num in sortdiff:
    print(num) ```

i actually cant find the error within this code 😭 also does anyone have a resource for learning other than leetcode and forums?

it is supposed to map tuples or integers

[lavish cave]

set.add should take a single value.

use set.update instead

or set |= other

m = int(input())
setm = set()
for _ in range(m):
    setm.update(map(int, input().split()))

n = int(input()) 
setn = set()
for _ in range(n):
    setn.update(map(int, input().split()))

symdiff = setn.symmetric_difference(setm)
sortdiff = sorted(symdiff)

for num in sortdiff:
    print(num)

ah i see

it still says this tho 😔

Traceback (most recent call last):
File "Solution.py", line 4, in <module>
EOFError

what does that even mean 💀

[lavish cave]

How are you running it?

EOFError means it reached the end of the file before it read anything

!e input()

[zenith dagger]

:x: Your 3.12 eval job has completed with return code 1.

:warning: Note: input is not supported by the bot :warning:

001 | Traceback (most recent call last):
002 |   File "/home/main.py", line 1, in <module>
003 |     input()
004 | EOFError: EOF when reading a line

[lavish cave]

python bot doesn't attach stdin, so it can't read it

That looks familiar, right?

[lethal condor]

ohhhh yeah

so how can i fix it?

[lavish cave]

How are you running it?

Running python in a terminal will always attach stdin

[lethal condor]

uhhh im running it on some kind of training website

it works on vscode tho

[lavish cave]

Then it probably doesn't give you a terminal.

[lethal condor]

is there even any fix to that?

[lavish cave]

probably not.

see if there's an FAQ about this on your website

[lethal condor]

alright, thank you for the help
