Many novice programmers think that if you write
if a==""ноль"" or ""нулевой"":then a will be compared sequentially with both parts - both with ""ноль"" and with ""нулевой"".
if a==""ноль"" or if a == ""нулевой"":In fact, the original line is nothing more than
if (a==""ноль"") or (""нулевой""):Therefore, there will be only one comparison: a == ""ноль"". The second part (""нулевой"") is simply evaluated for a boolean result, which in this case is always True ().
