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.

This is going to cause a lot of problems

yeah

quasi wraith
#

it might look like a 5x8 board

#

im not that familar with python as i am with java, this is my first time making a 2d list

quasi wraith
#

wait nevermind, this is ok, sorry

mental yoke
#

but there doesnt seem to be an issue with it

quasi wraith
#

I thought the list comp was duplicating the list

mental yoke
#

when i decreased row and col by one, it filled everything within nums except for the last 8 values in which they were still 0s
