Answer 1

You can use

re.findall(r"\$\d+(?:\.\d+)?|\d+(?:\.\d+)?\$", msg_content)

Details:

• \$\d+(?:\.\d+)? - $ char, one or more digits and then an optional sequence of a . and one or more digits
• | - or
• \d+(?:\.\d+)?\$ - one or more digits and then an optional sequence of a . and one or more digits and then a $ char.
