regex:finding a forbidden char in python code

I need to use a regex will determine if a single line of python code contains an illegal char '$'. But its allowed to appear in a comment or as part of a string. Meaning:

"legal char $" illegal $ #legal $

The above line should fail because it has a $ that isn't part of a string or a comment. If I remove it, and get

"legal char $" legal #legal $

This line should pass.

Illegal: Check for a .*$.*#? after creating a temporary string by using re.sub to replace \".*?\" in the line with an empty string.

Legal: not Illegal :) or [^$]*#?
