Hey there,
Please update the message to include your code. The code was too long to be automatically inserted by the help button.
When you enter a code, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

you can check your output vs the expected one using this: (repr puts the string all on line for easier comparison)
print("actual ", repr(arithmetic_arranger(["3801 - 2", "123 + 49"])))
print("expected", repr(" 3801 123\n- 2 + 49\n------ -----"))
currently it prints this:
actual ' 3801 123\n- 2 + 49\n------ ----- '
expected ' 3801 123\n- 2 + 49\n------ -----'
do you see the differences between the two strings?
I went ahead and combined your posts for you. In the future, just reply to the original thread to add further updates.
