I am trying to make functional queries to q by passing where condition.
when
in q:

fn:{[c]
    t: (select from tbl);
    :?[t;c;0b;()];
}

in Python

c = [['=', numpy.string_('TradeId'), 123456]]
result = conn.sendSync('fn', c)

the operator is passed as a string. I have tried with sending this as a symbol, as a Qfunction but doesn't work
