Each of which is invalid syntax, because whatever was used to compose
the message has replaced some characters.

    >>> if k + ‘_@‘ in documents:
      File "<stdin>", line 1
        if k + ‘_@‘ in documents:
                ^
    SyntaxError: invalid character in identifier
    >>> timeKey = k + ‘_@‘
      File "<stdin>", line 1
        timeKey = k + ‘_@‘
                       ^
    SyntaxError: invalid character in identifier
    >>> historyKey = thingID + ‘_’ + k
      File "<stdin>", line 1
        historyKey = thingID + ‘_’ + k
                                 ^
    SyntaxError: invalid character in identifier

If those characters are not the same as what the original poster is
seeing, then the rest of us should not be guessing about any of the
characters in that code.

Essential to asking for help with some program code is using tools that
reliably transmit the exact same characters to whoever one is asking for
help.
