This is my solution in Python3

def remove_dollar(string: str) -> float:
  remove_char = string.replace('$', '' ).replace(' ', '')
  return float(remove_char)

EDIT: Removed space, thanks for correcting me guys

you alse need to remove space from the string to avoid the exception

This was great, but failed (Python 3.8) the first test due to the added space - added an additional replace and passed all tests.

def remove_dollar(string:str) -> float:
  remove_char = string.replace('$', '').replace(' ', '')
  return float(remove_char)

You could also use the method strip

return float(string.strip("$"))

strip doc:

S.strip([chars]) -> str

Return a copy of the string S with leading and trailing
whitespace removed.
If chars is given and not None, remove characters in chars instead.

This doesn't work with string = "-$ 0.1" isn't it? I'd rather prefer the replace way :P
