Or, more directly, string.replace(this_string, '@', '').

However, repeated applications of these idioms are sub-optimal if the goal
is to remove all occurrences of all characters in a set, as the original
poster
suggested.  string.translate is optimal for that.

    identity=string.maketrans('','')    # no transformations required
    string.translate(this_string, identity, '@!$%{}')

This will perform exactly the stated request.
