Answer 2

I think you can do like this,
def strip_chars(st):
return "".join(c for c in st if c.isalpha() or c.isspace())

What symbol am I missing

Answer 6

OK, Nathan. There is no problem to be novice here.
I mean regular expression library, it is imported as "import re" in the first line of your program.

Answer 7

I hide the line "x = input()" and added x from the challenge.
You can uncomment it.

Answer 8

You should import re.

Answer 9

Nathan, I am confused asking: why did you write twice every symbol in chars?

Answer 10

It wasn't working with singular on my computer's IDE and I read somewhere if you repeat some symbols it would work

Answer 11

Would be it not easier to turn over your solution and test a character if it is letter or space?
