A unary operator has one operand; a binary operator has two operands; a ternary operator has three operands. Python has none built-in, although one can 'synthesize' all sorts of ternary operators by combining two binary operators, with the operand of one being the result of the other. However, people often don't think of such combinations as being such. Since C has one builtin ternary 'operator' (if-else), the term 'ternary operator' is too often used as a synonym for that particular example of a ternary operator. Others have referred you to discussions of if-else expressions in Python. Ironically, if one thinks of or defines an operator as being a function called without parenthesis, then C's ';:' and Python's 'and..or' are not really ternary operators but flow control expressions equivalent in effect to certain if/else statement pairs. That is because some of the operands may not be evaluated. That is also why there are no special methods corresponding to 'and' and 'or'. They are directly compiled to conditional code with no a function call corresponding to the 'operator'. Terry J. Reedy -- http://mail.python.org/mailman/listinfo/python-list
