Encoding error that only shows in the Interactive Window

Question

Summary

I am making a program in python, and I've finished it, ran it in shell and it worked perfectly. However when I run the program in the Interactive Window, it produces an error while in the idle window, it doesn't.

Crash information

Picture of the error before the window crashes:

Line 169 is a call for a subroutine

Line 30 is an end of a print shaped like this:

print(
"""
*text here*
"""
)

And the line 12 seems to refer to a program in the python files. In the program it imports a variable from a python program in the same location as this question.

The imported file is this:

ourMotto = ('You have been playing for over an hour. Please do not forget to take a break.')

It writes to a text file in the same file location named:

MichelleMooseCoffeeOrders

If you need me to add any more information about the program or help me format this question, then leave a comment. (I'm new to stack overflow and am still learning how to format questions so feedback helps)

error code after utf-8 encoding:

Alternatively, you can try adding this: `# -*- coding: utf-8 -*-` to the top of your code without getting rid of the euro sign! See [this](https://www.python.org/dev/peps/pep-0263/) link for more info on what the above line means. — Ubdus Samad, Jan 24 '18 at 12:57
In case if utf-8 doesn't work, try `# -*- coding: latin-1 -*-` instead of the utf-8 one. — Ubdus Samad, Jan 24 '18 at 12:59
The same error as before -- `#-*- coding: utf-8 -*-` doesn't work so I'll try latin-1 — ImpendingStorm, Jan 24 '18 at 13:02
I've tried `# -*- coding: latin-1 -*-` and it gives the same error as before in the interactive window I have included the # sign btw — ImpendingStorm, Jan 24 '18 at 13:05
I have added it to the end of the question. Sorry if the spacing is incorrect as i had to copy it from a picture that was gotten from a screenshot from the interactive window before it crashed — ImpendingStorm, Jan 24 '18 at 13:27
The euro sign is still there somewhere! At the last line of the stack trace (error text) you see `'\u20ac'` somewhere right? That's the Euro sign character. — Ubdus Samad, Jan 24 '18 at 13:29
I was just removing ones in the bit that was writing to the text file. I'll get rid of ALL euro signs. — ImpendingStorm, Jan 24 '18 at 13:31
It works! But is there a way to keep it in without it giving an error? Oh sorry I just saw that you said to do the utf-16 first. I'll put one back in and try the encoding — ImpendingStorm, Jan 24 '18 at 13:33
Added 1 euro back into the code, still gives an error with the utf-16 encoding — ImpendingStorm, Jan 24 '18 at 13:35
That's what I think these encoding declarations will do, they let you keep those weird signs without any error but, I think I am missing something. Can you E-mail me the code? — Ubdus Samad, Jan 24 '18 at 13:36
Wait a bit, let me check some internet resources first! btw it's ubdussamad @ google mail . — Ubdus Samad, Jan 24 '18 at 13:38
email me first at: '15CWhitehead@roydshall.org' when you've looked at some internet resources — ImpendingStorm, Jan 24 '18 at 13:40
Okay, I think I have it, where ever you have a print or string declaration which has a euro sign just attach `.encode("utf-8")` at the back of it. Like `print("Hello world".encode("utf-8"))` or `string = 'Hello world".encode("utf-8")` — Ubdus Samad, Jan 24 '18 at 13:42

What do you mean by array? What does an array has to do with encoding problem? — Ubdus Samad, Jan 24 '18 at 13:54
I have an array and in one of the values it has a euro sign at the end of it. What do it do for the encode here? — ImpendingStorm, Jan 24 '18 at 13:55
Ran it, when it came to the first place with euros with my encoding it printed this: b'\n What size would you like your coffee?\n Small - 2\xe2\x82\xac, Medium - 3.50\xe2\x82\xac, Large - 4.75\xe2\x82\xac, or Spicy - 5.25\xe2\x82\xac\n ' — ImpendingStorm, Jan 24 '18 at 13:56
Hahaha, My apologies for the crappy encoded output. Let me see if someone more experienced than me can help! — Ubdus Samad, Jan 24 '18 at 14:00
